+# Motion Design Skill
+
+## When to Apply
+
+Use this skill when:
+- Creating UI animations (buttons, cards, modals, page transitions)
+- Designing micro-interactions and feedback animations
+- Building loading, success, or error states
+- Animating illustrations or decorative elements
+- Planning scroll-triggered or progress-based animations
+- Establishing brand motion identity
+- Choreographing multi-element sequences
+
+**Decision tree:**
+1. Does it serve a functional purpose (feedback, guidance)? → Timing rules for responsiveness
+2. Does it express brand personality? → Motion Personality archetypes
+3. Does it tell a story or guide attention? → Disney principles + choreography
+4. Is this a complex multi-element scene? → 1/3 Rule + stagger patterns
+
+---
+
+## Quick Reference: 8-Step Checklist
+
+Before creating any animation:
+
+1. **Emotional target?** — joy, calm, urgency, elegance
+2. **Motion Personality?** — Playful, Premium, Corporate, Energetic
+3. **Primary property?** — position, scale, rotation, opacity
+4. **Duration?** — see duration table below
+5. **Easing family?** — entrance=decelerate, exit=accelerate
+6. **Hero element?** — apply staging principles
+7. **Secondary + ambient layers?** — add richness
+8. **1/3 rules?** — motion distance, simultaneous elements
+
+---
+
+## Three Pillars (CRITICAL)
+
+Every animation must satisfy three pillars before any technical decisions:
+
+| Pillar | Question | Drives |
+|--------|----------|--------|
+| **Emotional Intent** | What should the viewer FEEL? | Easing, timing, amplitude |
+| **Visual Narrative** | What's the micro-story? | Setup → Action → Resolution |
+| **Motion Craft** | How do we make it believable? | Physics, secondary motion, paths |
+
+**Three motion layers** (flat animation = missing layers):
+- **Primary**: Main action the viewer follows
+- **Secondary**: Supporting richness (shadows, icons shifting)
+- **Ambient**: Background life (gradients, subtle pulses)

+
+## Motion Personality
+
+Select ONE archetype per project. Apply consistently.
+
+| Archetype | Duration | Easing | Overshoot | Keywords |
+|-----------|----------|--------|-----------|----------|
+| **Playful** | 150-300ms | ease-out-back | 10-20% | fun, whimsical, bouncy, cute |
+| **Premium** | 350-600ms | cubic-bezier(0.4,0,0.2,1) | 0% | elegant, minimal, luxury, sophisticated |
+| **Corporate** | 200-400ms | cubic-bezier(0.2,0,0,1) | 0-3% | clean, professional, business, dashboard |
+| **Energetic** | 100-250ms | ease-out-expo | 15-30% | dynamic, energetic, bold, exciting |
+
+**Default**: Corporate for UI, Playful for illustrations.
+
+**Brand Motion Identity** — define three constants:
+1. **Signature easing**: One curve for 80% of animations
+2. **Duration palette**: 3 durations (quick / standard / slow)
+3. **Entrance pattern**: One consistent entry style

+## Property Selection
+
+| Effect Goal | Primary Property | Secondary Properties |
+|-------------|------------------|---------------------|
+| Entrance/Exit | position | opacity, scale |
+| Emphasis/Attention | scale | rotation (subtle), opacity pulse |
+| State Change | opacity, color | scale (press feedback) |
+| Direction/Flow | position | rotation (follow path) |
+| Depth/3D Feel | scale + shadow | position (parallax) |
+| Loading/Progress | rotation (spinner) | scale, opacity pulse |
+| Success | scale (pop) | color, rotation (checkmark draw) |
+| Error/Alert | position (shake) | color, rotation (wobble) |
+
+**Simplicity threshold**: Use the minimum properties needed. One = direct. Two = polished. Three+ = potentially overwhelming.

+
+## Duration Table
+
+| Element Type | Duration | Rationale |
+|-------------|----------|-----------|
+| Tooltip / micro-feedback | 80-120ms | Must feel instant |
+| Button press / toggle | 120-180ms | Responsive feedback |
+| Icon transition | 150-250ms | Clear state change |
+| Card enter / exit | 200-350ms | Spatial awareness |
+| Modal / dialog | 300-400ms | Focus shift |
+| Page transition | 400-600ms | Context switch |
+| Dramatic reveal | 600-1200ms | Theatrical build |
+
+**Distance scales duration**: 100px = base. 200px = 1.3x. 400px = 1.6x.
+
+**Enter > Exit**: Entrances 30-50% longer than exits. Users care about what appears.
+
+**Interactive feedback**:
+- Hover: <100ms
+- Press: <150ms
+- Release/settle: 200-300ms
+- Error shake: 300-400ms (2-3 oscillations)
+
+> Deep dive: [reference/timing-easing-tables.md](reference/timing-easing-tables.md)
+

+
+## Easing Selection
+
+**Directional rules**:
+- **Entrance** → decelerate (fast start, gentle landing): ease-out family
+- **Exit** → accelerate (gentle start, fast departure): ease-in family
+- **On-screen** → smooth both ends: ease-in-out family
+- **Looping ambient** → seamless: sine-based ease-in-out
+
+**Industry standards**:
+
+| Standard | Cubic Bezier | Use For |
+|----------|-------------|---------|
+| Material Design 3 | (0.2, 0, 0, 1) | Default on-screen |
+| MD3 Emphasized | (0.05, 0.7, 0.1, 1) | Entrances, attention |
+| MD3 Accelerate | (0.3, 0, 1, 1) | Exits, dismissals |
+| Apple HIG | (0.25, 0.1, 0.25, 1) | Standard iOS |
+| Snappy UI | (0.2, 0, 0, 1) | Fast, decisive |
+| Gentle float | (0.4, 0, 0.2, 1) | Ambient, background |
+| Bounce settle | (0.175, 0.885, 0.32, 1.275) | Overshoot, playful |
+
+**Material-based easing**:
+
+| Material | Duration Scale | Overshoot |
+|----------|---------------|-----------|
+| Rigid (metal, stone) | 1.2x | 0% |
+| Elastic (rubber, gel) | 0.8x | 15-25% |
+| Fluid (water, paint) | 1.5x | 5% |
+| Paper (cards, sheets) | 1.0x | 3-5% |
+| Gas (smoke, fog) | 2.0x | 0% |
+| Glass (brittle) | 0.9x | 0% |
+
+> Deep dive: [reference/timing-easing-tables.md](reference/timing-easing-tables.md)
+
+---
+
+## Common Patterns
+
+### Button Press (Playful)
+1. **Anticipation**: Scale to 0.97 (50ms, ease-out)
+2. **Squash**: Scale to [1.04, 0.96] (100ms, ease-in)
+3. **Follow through**: Overshoots to 1.02, settles to 1.0 (spring, 200ms)
+4. **Secondary**: Shadow shrinks during press, icon shifts down 2px
+5. **Total**: ~150ms press + 200ms settle
+
+### Card Entrance (Premium)
+1. **Start**: 20px below target, opacity 0
+2. **Path**: Slight curve (10px X offset at midpoint)
+3. **Easing**: ease-out-cubic deceleration
+4. **Follow through**: Shadow arrives 50ms after card
+5. **Secondary**: Content fades in 100ms after card lands
+6. **Staging**: Other cards dim to 80%
+
+### Success State (Playful)
+1. **Primary**: Scale pop with ease-out-back
+2. **Secondary**: Checkmark draws in
+3. **Ambient**: Subtle particle burst
+4. **Color**: Green fill
+5. **Total**: 300-400ms
+
+### Error Shake (Corporate)
+1. **Primary**: Position oscillates 2-3 times, ±10-15px horizontal
+2. **Easing**: ease-in-out for sharp stops
+3. **Color**: Red tint
+4. **Total**: 300-400ms
+5. **No overshoot**: Errors feel firm

+
+## Choreography Essentials
+
+**Coordinated entry**:
+- Lead with the hero — primary element enters first or most prominently
+- Spatial consistency — all elements enter from same direction
+- Counter-motion — hero moves right → ambient moves left at 20-30% speed
+
+**1/3 Rule (distance)**: No motion travels more than 1/3 of screen without a keyframe change.
+
+**1/3 Rule (elements)**: With 3+ elements, no more than 1/3 in active motion simultaneously.
+
+**Stagger budgets**:
+
+| Pattern | Delay | Total Budget | Use Case |
+|---------|-------|-------------|----------|
+| Micro cascade | 20-40ms | <200ms | List items, grid cells |
+| Standard | 50-100ms | <400ms | Cards, panels, nav |
+| Dramatic | 100-200ms | <600ms | Hero sections |
+| Wave | 30-60ms | <500ms | Data visualizations |
+
+**Critical**: Total stagger must stay under 500ms.

+## Emotion-to-Motion Map
+
+| Emotion | Character | Path | Easing | Duration |
+|---------|-----------|------|--------|----------|
+| Joy | Bouncy, arcs | Curved, upward | ease-out-back | 200-400ms |
+| Calm | Smooth, flowing | Gentle curves | sine ease-in-out | 500-1000ms |
+| Urgency | Sharp, fast | Straight lines | ease-out | 100-200ms |
+| Sadness | Slow, downward | Drooping curves | cubic ease-in-out | 600-1200ms |
+| Surprise | Sudden, expanding | Radial outward | ease-out-expo | 150-300ms |
+| Elegance | Slow, controlled | Long arcs | (0.4,0,0.2,1) | 400-700ms |
+| Playfulness | Bouncy, irregular | Arcs, squiggly | ease-out-back | 200-350ms |
+
+**Path as language**: Angular = tense. Curved = friendly. Spiral = whimsical. Diagonal = purposeful. Vertical = growth/weight. Horizontal = progress.

+
+## Weight Classification
+
+| Weight | Examples | Duration | Overshoot | Easing |
+|--------|----------|----------|-----------|--------|
+| Heavy | Modals, overlays | 300-500ms | 0% | Gentle, high damping |
+| Medium | Cards, panels | 200-350ms | 3-5% | Moderate |
+| Light | Tooltips, badges, icons | 80-200ms | 5-15% | Responsive |
+
+---
+
+## Quality Rules
+
+### CRITICAL — never break
+1. **Never linear for spatial movement** — always use easing curves (linear only for spinners, progress bars)
+2. **Never opacity-only** for important state changes — combine with position or scale
+3. **Never exceed 1/3 screen** without intermediate keyframe
+4. **Always three motion layers** — primary + secondary + ambient
+
+### HIGH — strongly follow
+1. Match duration to element type (see tables)
+2. Use directional easing (ease-out entrance, ease-in exit)
+3. Apply Disney principles (especially anticipation, follow-through)
+4. Maintain consistent personality across scene

+
+## Troubleshooting Quick Reference
+
+| Problem | Likely Cause | Fix |
+|---------|-------------|-----|
+| Looks robotic | Linear easing or no arcs | Add easing curves + arc paths |
+| Feels too slow | Duration too long for element type | Check duration table, use ease-out |
+| Feels cheap/flat | Missing secondary + ambient | Add shadow motion + background life |
+| Too distracting | Too many elements moving | Apply 1/3 rule, reduce amplitude |
+| No personality | Generic easing everywhere | Apply personality archetype consistently |

+# Choreography
+
+## Coordinated Entry Rules
+
+### 1. Lead with the Hero
+- Hero gets largest displacement and most attention-grabbing easing
+- Supporting elements are subtler in every dimension
+
+### 2. Spatial Origin Consistency
+All elements enter from same direction or shared origin. Mixed directions = chaos.
+
+### 3. Counter-Motion
+
+| Hero Motion | Counter-Motion | Speed Ratio |
+|-------------|---------------|-------------|
+| Enters left | Background shifts right | 20-30% |
+| Scales up | Shadow scales down | 10-20% |
+| Rotates CW | Ambient drifts CCW | 15-25% |
+| Lifts (Y up) | Shadow spreads + softens | 20-30% |
+
+## Sequence Structure
+
+| Phase | Duration Share | What Happens |
+|-------|--------------|-------------|
+| Setup | 20-30% | Elements enter, scene establishes |
+| Action | 30-40% | Primary motion, hero moment |
+| Resolution | 30-40% | Settle, secondary reactions, breathing |
+
+Leave 100-200ms stillness after resolution before new motion.
+
+## The 1/3 Rules
+
+**Distance**: No motion travels >1/3 screen without intermediate keyframe. Break with direction changes, speed variations, or arc adjustments.
+
+**Elements**: With 3+ animated elements, max 1/3 active simultaneously. Stagger so element 1 settles as element 3 starts.
+
+## Stagger Patterns
+
+| Pattern | Description | Best For |
+|---------|------------|----------|
+| Sequential | Reading order | Lists, grids |
+| Center-out | Radiating from center | Hero content, ripples |
+| Random | Varied timing | Organic, particle-like |
+| Wave | Sine-based | Data bars, continuous |
+| Reverse | Bottom-to-top | Exits, backward nav |
+
+- All staggered elements use same easing family
+- Vary only start time, not curve
+- Optional: last element gets slight overshoot (punctuation)
+
+## Shared Motion Events
+
+When multiple elements react to one trigger:
+- All start within 50ms of each other
+- Can arrive at different times (staggered landing)
+- Same easing family; motion originates from trigger point
+
+## Attention Direction
+
+| Technique | Implementation |
+|-----------|---------------|
+| Leading motion | Animate target before context |
+| Following motion | Settle on focal point |
+| Ambient motion | Subtle continuous in periphery |
+| Pointing motion | Directional toward CTA |
+
+### Depth Through Speed
+
+| Layer | Displacement | Speed |
+|-------|-------------|-------|
+| Foreground | 1.0x | Fastest |
+| Midground | 0.5x | Medium |
+| Background | 0.2x | Slowest |
+
+## Common Recipes
+
+### Dashboard Load
+1. Skeletons fade in (100ms)
+2. Hero metric (250ms, ease-out, 100ms delay)
+3. Supporting cards stagger (50ms between, 200ms each)
+4. Chart data draws in (300ms, starts with cards)
+5. Ambient pulse on primary metric
+
+### Modal Open
+1. Background dims (200ms)
+2. Modal scales 95%→100% + fades (300ms, 50ms delay)
+3. Content fades in (200ms, 100ms after modal)
+4. Close button last (150ms)
+
+### List Update (item added)
+1. Existing items shift down (200ms, ease-in-out)
+2. New item fades+slides from top (250ms, ease-out, 50ms delay)
+3. Subtle scale overshoot on land (3-5%)

+| Platform | Duration Modifier | Complexity | Physics |
+|----------|------------------|------------|---------|
+| Desktop | 1.0x (baseline) | Full | All types |
+| Tablet | 0.9x | Standard | Most types |
+| Mobile | 0.8x | Reduced (1-2 properties) | Snappy only |
+| Watch | 0.6x | Minimal (1 property) | None |
+| TV/Kiosk | 1.3x | Full | All types |
+
+**Mobile rules**: prefer opacity + transform; touch feedback <100ms; reduce stagger budgets by 30%; avoid parallax
+**Desktop opportunities**: hover states, cursor tracking, multi-column stagger, spatial choreography
+
+## Accessibility
+
+### prefers-reduced-motion
+
+| Original Motion | Reduced Alternative |
+|----------------|-------------------|
+| Slide entrance | Opacity fade only |
+| Bounce/spring | Instant or simple ease-out |
+| Parallax | Static positioning |
+| Auto-playing | Paused, user-initiated |
+| Complex choreography | Single fade |
+| Continuous ambient | Static or subtle opacity pulse |
+
+Reduced motion means: remove spatial movement, keep opacity, remove spring easing, reduce duration 50%+, never auto-play loops.
+
+### Vestibular Triggers (avoid or provide alternatives)
+- Large-scale zoom, full-screen position transitions
+- Spinning elements >100px, parallax >2 layers, rapid direction changes
+
+### Cognitive Accessibility
+- Same interaction = same animation every time
+- Pause controls for animations >5 seconds
+- Don't convey critical info through motion alone
+
+## Performance Budgets
+
+| Tier | Properties | Max Elements |
+|------|-----------|-------------|
+| Optimal | transform, opacity | Unlimited (GPU) |
+| Good | + color, clip-path | 10-15 |
+| Acceptable | + width, height, margin | 5-8 |
+| Avoid | box-shadow, border-radius, filter | 1-3 |
+
+- Target 60fps (16.67ms/frame); animation logic <10ms/frame
+- will-change sparingly; keep animated elements <20 per viewport
+- Stagger reduces peak load vs simultaneous
+- Fallback: 30fps acceptable for ambient

+# Core Philosophy
+
+## Three Pillars
+
+### Pillar 1: Emotional Intent
+Define target emotion before choosing any property.
+
+| Emotion | Character | Timing | Easing |
+|---------|----------|--------|--------|
+| Trust | Smooth, predictable | 300-400ms | Gentle curves |
+| Delight | Bouncy, surprising | 200-300ms | Overshoot |
+| Urgency | Sharp, direct | 100-200ms | Snappy ease-out |
+| Calm | Slow, flowing | 500-1000ms | Sine curves |
+| Surprise | Sudden, explosive | 150-300ms | Exponential |
+| Confidence | Direct, decisive | 200-400ms | Strong ease-out |
+
+### Pillar 2: Visual Narrative
+
+| Phase | Duration Share | Purpose |
+|-------|--------------|---------|
+| Setup | 20-30% | Establish context, prepare viewer |
+| Action | 30-40% | Primary motion, hero moment |
+| Resolution | 30-40% | Settle, breathe, confirm |
+
+Even a 200ms tooltip fade has implicit setup→action→resolution.
+
+### Pillar 3: Motion Craft
+- Easing curves match emotional intent
+- Duration proportional to element size and distance
+- Arcs for organic, straight for mechanical
+- Secondary motion (shadows, related elements)
+- Nothing starts and stops all at once
+
+## Three Motion Layers
+
+| Layer | Role | Amplitude |
+|-------|------|-----------|
+| Primary | Main action viewer follows | 100% |
+| Secondary | Supporting richness | 30-50% |
+| Ambient | Background life | 10-20% |
+
+- Secondary offset 50-100ms from primary, different easing
+- Ambient is continuous/slow, never demands attention
+- Primary-only animation feels flat; always add secondary + ambient
+
+## The 1/3 Screen Rule
+No motion travels >1/3 screen without intermediate keyframe. Break with direction changes, speed shifts, or arc adjustments.
+
+## The Attention Budget
+- One hero motion per scene moment
+- Max 2-3 elements in active motion simultaneously
+- Ambient doesn't count against budget
+- Stagger rather than synchronize

+# Decision Framework
+
+## The First Questions
+
+### 1. Purpose?
+
+| Purpose | Approach | Priority |
+|---------|----------|----------|
+| Draw attention | Scale, color, pulse | Responsiveness |
+| Guide sequence | Stagger, directional flow | Clarity |
+| Provide feedback | Immediate response | Speed |
+| Create atmosphere | Subtle, continuous | Subtlety |
+| Explain relationship | Position, connection | Legibility |
+| Celebrate/reward | Overshoot, particles | Delight |
+
+### 2. Audience?
+- Stressed → calm motion; Browsing → richer motion
+- Task-focused → fast, minimal; Exploring → can be dramatic
+- Seen 100x/day → fast, subtle; Seen once → can be dramatic
+
+### 3. Context?
+- Busy layout → simpler motion; Empty → can be dramatic
+- Other animations active → coordinate or stagger
+- Small container → small motion
+
+## 4-Level Decision Hierarchy
+
+### Level 1: Motion Category
+
+| Category | When |
+|----------|------|
+| Revealing | Content appearing |
+| Concealing | Content disappearing |
+| Transitioning | Between states/views |
+| Emphasizing | Drawing attention |
+| Responding | Reacting to interaction |
+| Ambient | Background atmosphere |
+
+### Level 2: Motion Personality
+Match to brand. See [motion-personality.md](motion-personality.md).
+
+### Level 3: Motion Direction
+
+| Direction | Communicates |
+|-----------|-------------|
+| Upward | Growth, aspiration |
+| Downward | Settling, completion |
+| Leftward | Regression, departure |
+| Rightward | Progression, arrival |
+| Outward (scale up) | Importance, emergence |
+| Inward (scale down) | Dismissal, removal |
+| Center-seeking | Focus, convergence |
+| Center-fleeing | Distribution, release |
+
+### Level 4: Implementation Properties
+Choose animated properties. See [property-selection.md](../reference/property-selection.md).
+
+## Decision Quick-Path
+
+```
+1. PURPOSE → What does this motion DO?
+   ├── Feedback → short, ease-out, minimal
+   ├── Entrance → ease-out, personality-matched
+   ├── Exit → ease-in, 70% of entrance
+   ├── Emphasis → scale or color pulse
+   └── Ambient → slow, continuous, sine
+
+2. PERSONALITY → Match keywords
+   ├── Fun/bouncy → Playful
+   ├── Elegant/luxury → Premium
+   ├── Clean/professional → Corporate
+   └── Bold/dynamic → Energetic
+
+3. PROPERTIES → Minimum needed (two = sweet spot)
+
+4. TIMING → Check duration table, adjust for distance/weight
+
+5. EASING → Entering=ease-out, Leaving=ease-in, On-screen=ease-in-out, Looping=sine
+```
+
+## Evaluation Before Delivery
+
+| Check | Question |
+|-------|----------|
+| Purpose | Clear function? |

+# Disney's 12 Principles — UI Adapted
+
+## 1. Squash and Stretch
+
+- Squash: scale ~[1.2, 0.8]; Stretch: ~[0.85, 1.15]
+- Impact: 2-4 frames (30-65ms); Recovery: 4-8 frames (65-130ms)
+- Preserve volume: width +20% → height decreases proportionally
+- Skip for premium/luxury brands
+
+## 2. Anticipation
+
+- Small motion opposite to main direction before action
+- Duration: 100-200ms, magnitude: 10-20% of main action
+- Button: scale down 3% before expanding; Card: shift 5-10px away first
+- Skip for micro-feedback (<150ms)
+
+## 3. Staging
+
+- Dim non-hero elements to 40-60% opacity; optional 2-4px blur
+- Hero enters 100-200ms after supporting elements
+- One primary action per timing beat
+
+## 4. Straight Ahead vs. Pose to Pose
+
+| Approach | Feel | Best For |
+|----------|------|----------|
+| Straight Ahead | Fluid, spontaneous | Particles, ambient, generative art |
+| Pose to Pose | Planned, controlled | UI transitions, state changes |
+
+## 5. Follow Through and Overlapping Action
+
+- Child delay: 50-150ms behind parent
+- Trailing elements: offset stop times by 100-200ms
+- Use spring easing for trailing parts (lower stiffness = more trailing)
+
+## 6. Slow In and Slow Out
+
+| Context | Easing | Why |
+|---------|--------|-----|
+| Entrance | ease-out | Arrives smoothly |
+| Exit | ease-in | Departs quickly |
+| On-screen | ease-in-out | Smooth journey |
+| Ambient loop | sine ease-in-out | Seamless |
+
+**NEVER** linear for spatial movement. Linear only for: rotation, progress bars, timers.
+
+## 7. Arcs
+
+- Add 10-20px perpendicular offset at path midpoint
+- Subtle (5px) for corporate, pronounced (20px+) for playful
+- Mechanical UIs can use straight paths intentionally
+
+## 8. Secondary Action
+
+- Amplitude: 30-50% of primary; timing: 50-100ms after primary
+- Different easing than primary
+- Examples: card enters → shadow grows; button presses → ripple expands
+
+## 9. Timing
+
+| Weight/Mood | Duration |
+|-------------|----------|
+| Heavy (modals, pages) | 400-800ms |
+| Light (tooltips, toggles) | 100-250ms |
+| Sad/serious | 600ms+ |
+| Happy/light | 200-400ms |
+| Urgent | 100-200ms |
+
+Enter-exit asymmetry: entrances 30-50% longer than exits.
+
+## 10. Exaggeration
+
+| Personality | Exaggeration |
+|-------------|-------------|
+| Playful | 15-25% |
+| Energetic | 20-30% |
+| Corporate | 0-5% |
+| Premium | 0% |
+
+- Scale overshoot: 10-30% beyond target; rotation: ±5-15°
+
+## 11. Solid Drawing
+
+- Maintain consistent proportions across keyframes
+- Use scale + rotation together for depth
+- Shadow behavior matches implied light source
+
+## 12. Appeal
+
+- Smooth curves over sharp angles; satisfying timing
+- Personality consistency across all elements
+- Appeal killers: jerky motion, inconsistent timing, abrupt stops, uniform animation
+
+## Combining Principles
+
+| Recipe | Principles Used |

+# Narrative Structure
+
+## Four-Act Structure
+
+### Act 1: Anticipation (10-20%)
+- Wind-up: small motion opposite to main direction
+- Gathering: elements pull together before dispersing
+- Dimming: context fades for focus; Tension: hold compressed ~50ms
+- Skip for <150ms interactions and hover states
+
+### Act 2: Action (30-50%)
+Peak energy. The primary communicative motion.
+- Fast+direct (sharp easing) → alerts
+- Smooth+flowing (gentle easing, curves) → transitions
+- Explosive+expanding (expo, radial) → celebrations
+- Controlled+precise (linear-ish) → data charts
+
+### Act 3: Reaction (10-20%)
+- Shadows adjust: 50-100ms after primary
+- Siblings shift: 50-150ms after primary
+- Environment ripples: 100-200ms after primary
+- Counter-motion: simultaneous with action
+- Skip for simple toggles/checkboxes
+
+### Act 4: Resolution (20-30%)
+- Overshoot settle (spring/back-easing); opacity reaches final (ease-out)
+- 100-200ms breathing room before next motion
+- Even 50ms of settling transforms the feel
+
+## Scaling to Duration
+
+| Total | Anticipation | Action | Reaction | Resolution |
+|-------|-------------|--------|----------|------------|
+| 100-200ms | skip | 60-70% | skip | 30-40% |
+| 200-400ms | 10-15% | 40-50% | 10-15% | 25-30% |

+| 800ms+ | 20% | 30-35% | 15-20% | 25-30% |
+
+## Multi-Beat Narratives
+
+Transitions: overlap (fluid) | sequential (clear) | simultaneous (parallel)
+
+Progressions:
+- **Build-Up**: low → rising → peak → settling
+- **Cycle**: depart → peak → return → repeat
+- **Impact**: sudden action → ripple → slow settle
+
+## By Personality
+
+| Personality | Anticipation | Action | Resolution |

+| Premium | Subtle tension | Smooth, controlled | Elegant ease |
+| Corporate | Minimal/none | Direct, efficient | Clean stop |

+
+## Common Patterns
+
+- **Reveal**: tension (dim, scale 95%) → emerge (100%, full opacity) → surroundings adjust → settled
+- **Departure**: gather (scale 98%) → exit → close gap → layout settles
+- **Transformation**: destabilize (vibration) → morph → secondary appears → new state breathing
+- **Celebration**: compress (50-100ms) → burst (scale, particles) → settle → calm with positive state

+# Ambient & Continuous Patterns
+
+Ambient amplitude: 10-20% of primary motion. Never compete for attention.
+
+## Breathing / Pulse
+
+- Scale oscillation 0.98-1.02, sine ease-in-out, 2000-4000ms/cycle
+- Alt: opacity oscillation 0.7-1.0
+
+| Context | Scale Range | Duration | Opacity Range |
+|---------|-----------|----------|--------------|
+| Active indicator | 0.95-1.05 | 2000ms | 0.6-1.0 |
+| Waiting/idle | 0.98-1.02 | 3000ms | 0.8-1.0 |
+| Background element | 0.99-1.01 | 4000ms | 0.9-1.0 |
+| CTA attention | 0.97-1.03 | 2500ms | 0.7-1.0 |
+
+Pulsing >±5% scale becomes attention-demanding.
+
+## Floating / Hovering
+
+- Y position ±5-15px, sine ease-in-out, 3000-5000ms/cycle
+- Optional: slight rotation ±2-3°, offset 30% of position cycle
+
+**Layered floating** (multiple elements — different durations prevent sync):
+- Element 1: 4000ms, ±10px
+- Element 2: 5500ms, ±8px (offset 30%)
+- Element 3: 3500ms, ±12px (offset 60%)
+
+## Gradient Shift
+
+- Background-position or gradient angle shift
+- Duration: 8000-20000ms/cycle; range: ±10-20% position or ±15° angle
+- Easing: linear or sine; should be imperceptible at a glance
+
+## Parallax
+
+| Layer | Speed Ratio | Content |
+|-------|------------|---------|
+| Foreground | 1.0x | Interactive, text |
+| Midground | 0.5x | Decorative, cards |
+| Background | 0.2x | Patterns, scenery |
+| Deep background | 0.1x | Texture, atmospheric |
+
+**Scroll-driven**: total displacement <100px; avoid on mobile; never parallax text
+**Mouse-driven**: foreground 10-20px max, background 5-10px opposite direction, 100-200ms interpolation
+
+## Continuous Rotation
+
+- Spinners: linear easing, 1000-2000ms/revolution
+
+| Variant | Speed | Use Case |
+|---------|-------|----------|
+| Slow spin | 10-30s/rev | Background decoration |
+| Gear-like | 3-5s/rev | Technical/mechanical |
+| Orbital | 5-15s/rev | Space/science theme |
+| Wobble | 2-4s/cycle, sine | Playful idle |
+
+## Shimmer / Gleam
+
+- Gradient sweep left-to-right, 1500-2500ms/sweep
+- Pause 2000-5000ms between sweeps
+- Opacity gradient: 0%→30%→0%
+- Use for: skeleton loading, premium accents, "new" badges
+
+## Particle Ambient
+
+### Snow/Falling: 10-20 elements, 20-60px/s down, ±10-20px drift, 3-8px, 30-70% opacity
+### Dust/Motes: 5-10 elements, 10-30px/s mixed, 2-5px, 20-50% opacity
+### Sparkle/Stars: 8-15 elements, opacity pulse 0→100%→0, 500-1500ms/sparkle, random stagger
+
+**Performance**: <20 ambient elements, transform+opacity only, larger/fewer over small/numerous
+
+## Combining Ambient Layers
+
+| Layer | Type | Example |
+|-------|------|---------|
+| Background | Gradient shift or parallax | Slow color temperature change |
+| Midground | Floating or particles | Gentle floating elements |
+| Foreground | Breathing or shimmer | Subtle pulse on content |
+
+Total ambient: max 20% of primary motion's visual energy.

+# Troubleshooting
+
+## Looks Robotic
+- Linear easing → use ease-out (entrance) or ease-in-out
+- Straight paths → add 10-20px arc at midpoint
+- Uniform timing → stagger 50-100ms between elements
+- Everything synced → offset start/stop 50-150ms
+- No secondary → add shadow, icon reaction, ambient
+
+## Feels Too Slow
+- Duration exceeds type budget → check duration table
+- ease-in-out when ease-out works → ease-out feels faster
+- Too much anticipation → reduce to 10% or remove
+- Stagger exceeded → total <500ms
+- Overshoot settle too long → increase damping
+
+## Feels Too Fast / Jarring
+- Duration below minimum → modals 300ms+, pages 400ms+
+- No easing → add ease-out minimum
+- Missing resolution → add 50-100ms settle
+- No anticipation on large motion → add 100-200ms wind-up
+
+## Feels Cheap / Flat
+- Only primary motion → add secondary + ambient
+- Opacity-only → combine with position or scale
+- Same easing everywhere → vary primary vs secondary
+- No follow-through → child elements trail 50-150ms
+- No overshoot → add 3-10%
+
+## Too Distracting
+- Too many moving → 1/3 rule
+- Amplitude too large → reduce to minimum
+- Competing heroes → one per moment, dim rest
+- Ambient too prominent → 10-20% amplitude, slower
+- No breathing room → 100-200ms pause between beats
+
+## No Personality
+- Default easing → apply archetype's signature
+- Same duration for all → use personality palette
+- No consistent entrance → define one for project
+- Mixed archetypes → pick one for 90%+
+
+## Inconsistent Feel
+- Different easing same-type → standardize per motion type
+- Duration varies same type → use palette consistently
+- Entry direction changes → one origin everywhere
+- Overshoot inconsistent → apply rules consistently
+
+## Performance (Dropped Frames)
+- Animating width/height/margin → use transform
+- Too many elements → <20 per viewport
+- Complex shadows/filters → simplify or pre-render
+- No GPU acceleration → transform + opacity
+- All simultaneous → stagger to spread load
+
+## Quick Diagnostic
+
+1. No linear on spatial movement
+2. Duration matches element type
+3. Primary + secondary layers
+4. Consistent personality
+5. Directional easing correct
+6. 1/3 screen rule
+7. 1/3 element rule
+8. Follow-through present
+9. Every motion has purpose
+10. Fine on 100th viewing
+
+## Personality Mistakes
+- **Playful**: overshoot >25% = broken; not everything bounces; short+bounce = glitchy
+- **Premium**: too subtle = invisible; too slow = waiting; zero = broken
+- **Corporate**: too conservative = boring; playful easing breaks trust; identical = monotonous
+- **Energetic**: max everywhere = nothing stands out; too many particles; no settle = chaos

+description: Create videos from React code with Remotion. Use when the user asks to make, animate, preview, or render a video, motion graphic, intro, caption, or social clip using code.
+---
+
+# Remotion Video
+
+Remotion makes videos out of React components. Each frame is a web page. Render them in order and you get an MP4.
+
+## Core ideas
+- **Composition**: one video. Has `width`, `height`, `fps`, `durationInFrames`.
+- **Frame**: `useCurrentFrame()` returns the current frame number. All animation is a function of the frame.
+- **`interpolate`**: maps a frame range to a value range (fade, slide).
+- **`spring`**: natural bouncy motion.
+- **`Sequence`**: shows children only during a frame range.
+- **`AbsoluteFill`**: full-screen layer; stack them for backgrounds.
+- **`Audio` / `OffthreadVideo` / `Img`**: media. Put files in `public/` and load with `staticFile("name.mp3")`.
+
+## Workflow
+1. **Plan first.** Ask or decide: length (seconds), size (1920x1080, or 1080x1920 for vertical), fps (30), and the scenes. Keep scenes to a short list.
+2. **Set up** (skip if the project exists):
+   ```
+   npx create-video@latest
+   cd <project> && npm install
+   ```
+3. **Write** compositions in `src/`, register them in `src/Root.tsx`.
+4. **Preview**: `npm run dev` (opens Remotion Studio).
+5. **Render**: `npx remotion render <CompositionId> out/video.mp4`
+   Still frame: `npx remotion still <CompositionId> out/frame.png --frame=30`
+6. **Verify**: render one still first, check it looks right, then render the full video.
+
+## Starter example
+`src/Root.tsx`
+```tsx
+import { Composition } from "remotion";
+import { Hello } from "./Hello";
+
+export const RemotionRoot = () => (
+  <Composition
+    id="Hello"
+    component={Hello}
+    durationInFrames={150}
+    fps={30}
+    width={1920}
+    height={1080}
+    defaultProps={{ title: "Hello, world" }}
+  />
+);
+```
+
+`src/Hello.tsx`
+```tsx
+import { AbsoluteFill, interpolate, spring, useCurrentFrame, useVideoConfig } from "remotion";
+
+export const Hello = ({ title }: { title: string }) => {
+  const frame = useCurrentFrame();
+  const { fps } = useVideoConfig();
+  const opacity = interpolate(frame, [0, 30], [0, 1], { extrapolateRight: "clamp" });
+  const scale = spring({ frame, fps, config: { damping: 12 } });
+
+  return (
+    <AbsoluteFill style={{ backgroundColor: "#0b1020", justifyContent: "center", alignItems: "center" }}>
+      <h1 style={{ color: "white", fontSize: 120, opacity, transform: `scale(${scale})` }}>{title}</h1>
+    </AbsoluteFill>
+  );
+};
+```
+
+## Rules of thumb
+- Never animate with CSS transitions, `setTimeout`, or CSS animations. They don't render per frame. Drive everything from `useCurrentFrame()`.
+- Always pass `extrapolateRight: "clamp"` to `interpolate` unless you want values to keep growing.
+- Seconds to frames: `seconds * fps`.
+- Use `<Sequence from={..} durationInFrames={..}>` to order scenes; `<Series>` to chain them.
+- Load fonts with `@remotion/google-fonts` so they are ready before rendering.
+- Keep props in `defaultProps` so the user can edit text in the Studio.
+- Rendering needs Chromium and ffmpeg (Remotion installs/handles these); first render can be slow.
+
+## Fonts
+Google Fonts: `npm i @remotion/google-fonts`, then
+```tsx
+import { loadFont } from "@remotion/google-fonts/Inter";
+const { fontFamily } = loadFont();   // use as style={{ fontFamily }}
+```
+It downloads the font while rendering, so the machine needs internet access to fonts.googleapis.com. If the render fails with "Failed to load font", the network is blocking it: use a local font file in `public/` with `@remotion/fonts` (`loadFont({ family, url: staticFile("x.woff2") })`) or a system font. (Not verified in the sandbox where this skill was tested, which had no access to Google.)
+
+## Common problems
+- **Can't download the browser (no internet / locked-down machine)**: point Remotion at an installed Chromium:
+  `npx remotion render <Id> out/video.mp4 --browser-executable=/path/to/chromium --chrome-mode=chrome-for-testing`
+- **Blank/white frames**: an asset path is wrong; use `staticFile()`.
+- **Flicker**: an image or font not loaded; use `<Img>` and `@remotion/google-fonts`.
+- **Slow render**: lower resolution/fps while testing, or use `--concurrency`.
+
+## Templates
+Copy-paste starting points. Read the one that fits:
+- `templates/captions.md` - words highlighted in time with speech
+- `templates/charts.md` - animated bar chart
+- `templates/intro-outro.md` - title card + chaining scenes with `Series`
+- `templates/audio-voiceover.md` - background music, voiceover, auto video length
+- `templates/vertical.md` - 1080x1920 clips for Reels/TikTok/Shorts

+/>
+```
+
+Install: `npm i @remotion/media-utils`
+
+Getting a voiceover
+- Record yourself, or generate speech with a text-to-speech service, and save as `public/voice.mp3`. Never commit API keys; keep them in environment variables.
+- Pair with `templates/captions.md`: feed it word timings from a transcription of the same file.
+
+Rules
+- Music volume 0.1-0.2 so the voice stays clear.
+- `<Sequence from={...}>` delays when a sound starts.
+- Audio is only in the final render (mp4). Stills (`remotion still`) have no sound.
+- Check the sound made it in: `ffprobe out/video.mp4` should list an `Audio:` stream.

-# Animating Clawd
-
-Read this whole file before you draw anything. It covers how to make a short, hand-painted cartoon, starring Clawd or any character you design: the rules and animation principles that make it look good, the workflow that catches mistakes, and the full reference for the character and the engine.
-
-The person prompting you decides **what** the video is about. This guide decides **how** it's made. If they ask for something the rules below forbid (a caption, a 3D spin), do what they ask.
-
-**No design here is final.** Clawd, the emotions, the props and the helpers are a starting point, not a limit. Change any of them, Clawd's own design included, and add whatever new characters, props or emotions the idea needs. Paint new things with the same tools and rules, so they belong with the rest.
-
-Look at the model sheets first:
- [docs/emotions.jpg](docs/emotions.jpg): all 31 emotions.
- [docs/views.jpg](docs/views.jpg): the five key views, the motion helpers and the hats.
-
---
-
-## The three goals
-
-Every rule below serves one of three goals.
-
- **Handmade.** The video should look like someone painted it by hand, frame by frame. That means brush strokes, ink lines that boil, flat 2D and no lettering.
- **Alive.** Something is always moving and something is always happening. Faces act instead of snapping, and characters are big enough to feel.
- **One piece.** It's one short film, not a pile of clips. Plan it before you draw it, and link every scene to the next.
-
-Underneath all three, the viewer has to be able to follow it. Timing (rule 4) is the rule models get wrong most often.
-
-## The rules
-
-### 1. The medium is solid: brush strokes, flat 2D, boil
-
- **Paint everything with p5.brush through `paint()` and `inkLine()`.** Characters get flat `wash` colour plus an ink outline. Backgrounds get soft watercolour `fill` shapes, usually with no outline or a thin one. Never use plain p5 shapes (`rect`, `ellipse`, `fill()`): they look like 2000s Flash.
- **The linework boils.** `jit()` and `random()` are reseeded 12 times a second (`BOIL`), so every drawing wobbles slightly, like hand-drawn animation. That's the look; don't fight it. For anything that must stay put from frame to frame (star positions, tuft heights), use `hash(i)`. Give each separate element its own seed with `boilSeed(key)` (see Engine), or one moving thing makes everything drawn after it jitter.
- **Everything is flat 2D. Never project 3D.** Don't rotate a box in perspective, don't use `rotateY` or WEBGL 3D and don't fake depth with math. Clawd turns through **drawn key views** (front → 3/4 → side → back 3/4 → back), exactly like a cartoon model sheet: see `turn()` and `spinView()`. Depth comes from overlap, scale and colour (farther = smaller, bluer, paler), never from a projection.
- **Light is the one exception.** p5.brush mixes colour like pigment, so a yellow glow painted over blue turns green, and a thin wash over it turns grey. Use `glow()` for anything that shines: it adds real light, under the paper grain.
- **Soft palette, no pure black or white.** Use `PAL.ink` for black and `PAL.cream` or `PAL.paper` for white. Keep colours soft and harmonious, and keep Clawd clearly readable against the background.
-
-### 2. No text
-
- **Show it, don't write it.** Models overuse text. No captions, no titles, no labels on objects, no signs, no speech bubbles with words, no words on screens, no "ZZZ" typed in a font.
- **Clawd's reactions are painted marks, never letters**: `!`, `?`, zzz, sweat, hearts, a bulb, a rain cloud. Use the emotes (see the reference).
- **A sign that repeats the story is the classic failure.** If Clawd holds a sign saying "I'm lost", the shot has failed. Show Clawd being lost: looking left, then right, the map upside down, a sweat drop.
- If the prompt truly needs a word (a name, a shop sign that is the joke), use `letter()`. Paint it into the scene, keep it to one or two words and use it once.
-
-### 3. Something happens in every scene
-
- **Every shot needs an event:** something changes between its first frame and its last. Clawd wants something, finds something, tries, fails, reacts or gets it. "Clawd stands in a meadow being cute" is not a shot.
- **One focal action at a time.** Stage it with a clear silhouette and nothing competing for attention, so it reads at a glance.
- **Cause, then reaction.** When something happens, Clawd reacts to it: a take, an emotion change, a turn toward it. The reaction is often the funniest part, so give it time.
- **Pay it off.** Whatever you set up in a shot (a door, a sandwich, a strange noise) gets resolved on screen, in that shot or a later one.
-
-### 4. Timing: model the viewer
-
-Timing turns a set of drawings into a story. It's also where generated animation fails most often: everything moves at one brisk speed, events pile on top of each other, and moments are over before anyone understands them.
-
-You know what happens because you wrote the code. The viewer doesn't: they see it once, at full speed, for the first time. **For every moment, ask what the viewer needs to understand and how long that will take them, and time it for that.**
-
- **Write the reads.** For each shot, list in order what the viewer has to understand. Each item is a *read*. Every read needs time for the eye to find it, time to understand it, and a moment to register before the next thing starts. Small, distant, fast or subtle things take longer to find and understand than big, central, obvious ones.
- **One read at a time.** Don't start a new read while the viewer is still taking in the last one. When two things happen at once, the viewer sees only one of them. Put a cause and its reaction in sequence, not on top of each other.
- **Fast actions, slow meanings.** A motion can be very quick if it's anticipated, but what it means needs held time. Anticipation tells the viewer where to look before the action, and the hold after it lets them understand it. Move quickly through what doesn't matter to the story, and spend time on what does. That contrast between quick and held is what gives a film rhythm; one constant speed, fast or slow, makes it flat and hard to follow.
- **Lead the eye.** The viewer looks at whatever moves, is bright, is big or is being looked at. Before an important read, get their eye to the right place (a character looks at it, the camera moves to it, it moves or lights up first), and give the eye time to get there.
- **Let the reads set the length.** A shot is as long as its reads need. A shot with many reads can't be short, and a shot whose reads have all landed shouldn't be padded. That includes the last shot: its final read needs time to land before the video ends.
-
-For a worked example, see how the demo times its ending, at the end of this guide.
-
-### 5. Alive
-
- **Nothing is ever still.** Every emotion has its own idle motion (`feel()`), cameras drift or push, grass sways, stars twinkle and the linework boils. A frozen frame reads as a bug.
- **Faces act, they never snap.** Change moods with `emotions()`. It does anticipation, a squint, a take and overshoot around every change. Never swap `eyes`/`mouth` by hand between two frames.
- **Move like a cartoon, not a machine.** Every move follows the animation principles in the next section.
- **Clawd is big.** In a medium shot, `u` is about 20–28 (Clawd is 10u wide, 8u tall). In a close-up it's 40–70. Tiny Clawds (u < 12) are for wide establishing shots only, and never for the whole video.
- **Everything moves on a beat.** `PROJECT.bpm` drives every idle, bounce and dance, so the whole film shares one pulse. Put the hits on beats (`pulse()`, `beatN()`), even with no music.
-
-### 6. Transitions always
-
- **Every seam gets a transition:** into the first shot, between every pair of shots and out of the last one. Never start on a hard frame, and never just stop.
- **Pick a transition that belongs to the story**, and don't default to the same one every time. Some options:
-  - a brush wipe (`brushWipe`)
-  - an iris or shaped iris (`iris`, `irisShape`)
-  - a whip pan with a smear
-  - a match cut (the same shape or motion across the cut)
-  - a cut on action (cut mid-move, and finish the move in the next shot)
-  - a camera move that carries through into the next shot
-  - a fade or push from paper or black
- A plain cut is fine only when it's on action or a deliberate smash cut.
- **Changes inside a shot are transitions too:** emotions go through `emotions()` and turns go through `turn()`. Props arrive and leave on arcs, never popping in.
-
-### 7. One piece: a vision before any code
-
- **Storyboard first**, in writing, before you write any scene code (the workflow below has the format). If you're working with a person, show them the storyboard and let them react before you build.
- **One world.** Pick a palette and a setting that carries through, with a colour arc across the video (e.g. cold night → warm dawn as Clawd's mood lifts).
- **One thread.** The story has a beginning, a middle and an end, and Clawd's emotional arc follows it. Plan the emotion keys across the whole video, not per shot.
- **Rhyme the ending with the opening:** the same place, pose or motif, changed. It makes the film feel whole.
- **Link scenes:** motion continues across cuts, and screen direction stays consistent (if Clawd travels right, keep travelling right). Props and characters carry over.
-
---
-
-## Animation principles
-
-These are the classic principles of character animation, as they apply here. Most of them fix one problem: motion written as code comes out mechanical, because code moves every part at once, on the same curve, by the same amount.
-
- **Anticipation.** Before a big move, make a small move the opposite way: a crouch before a jump, a wind-up before a throw, a squint before a take. It tells the viewer something is coming and where to look. `jump()` and `emotions()` build it in.
- **Squash and stretch.** Bodies squash on impact and stretch when they move fast, keeping their volume (`sq`).
- **Slow in, slow out.** Almost nothing moves at a constant speed. Things ease out of one pose and into the next. A plain `lerp` over time looks mechanical, so run its progress through an easing (`ease`, `easeIn`, `easeOut`, `backOut`).
- **Weight.** How something starts and stops says what it weighs. Heavy things take longer to get going and to stop, and land with little bounce. Light things snap into motion, bounce and flutter to rest.
- **Arcs.** Living things move on arcs, not straight lines: thrown props, hops, arm swings, head turns (`arcPt`).
- **Overlapping action and follow-through.** Don't move every part at once. The eyes lead, the body follows, and arms, hats, props and tails drag behind, overshoot and settle last. Offset each part's timing a little from the one it hangs off (`spring`, `ring` and `backOut` for the settle).
- **Avoid twinning.** Code copies values, so both arms end up at the same angle, both eyes blink together and a crowd bounces in unison. Give one arm the action and the other something smaller, and offset timings, phases and `seed`s between characters.
- **Exaggeration.** Push poses, takes, squash and leans further than feels natural. In a short cartoon, subtle reads as nothing. If it looks like too much on the sheet, pull it back.
- **Strong key poses.** Each shot's storytelling poses should read as stills, with a clear silhouette and the body leaning into what it's doing, before any motion goes between them. If the key poses don't read, the motion won't fix it.
- **Show the thought.** A character notices, thinks, then acts, and the eyes move first. The viewer understands a choice when they see it being made.
- **Secondary action.** Small actions that support the main one (a hat bobbing, an emote popping, grass stirring) add life, but they never compete with it.
-
---
-
-## Workflow
-
-### 1. Storyboard
-
-Write `STORYBOARD.md` before any scene code:
-
-```
-Logline: one sentence. Clawd wants ___, but ___, so ___.
-World: setting, a small palette, light, how the colour changes across the video.
-Motif: the thing that recurs and pays off.
-Clawd's arc: the emotion keys across the whole video.
-Shots:
-  A  start–end  [transition in: ___]  what's seen · the EVENT · Clawd's reaction · camera
-     reads:  start–end  the first thing the viewer must understand
-             start–end  the next one (where is the viewer's eye when it starts?)
-             ...
-  B  start–end  [transition: ___]  ...
-  ...
-  [transition out: ___]
-```
-
-The reads are the timing sheet. Give each one a start and an end, make sure each has time to be found and understood, and make sure no two important reads overlap. If a shot's reads don't fit its length, lengthen the shot or cut a read; don't squeeze them.
-
-Check the storyboard against the rules:
- Is there an event in every shot?
- Does every read have time to land before the next one starts?
- Is there a transition at every seam?
- Is there any text anywhere?
- Does the ending rhyme with the opening?
-
-### 2. Build
-
- Set `duration` (and `bpm`) in [src/config.js](src/config.js).
- Put your scene in a new file (e.g. `src/scenes/my_video.js`), wrapped in an IIFE, and end it with `shots([...])`. In [studio.html](studio.html), **replace** the `demo.js` script tag with yours.
- Build and check one shot at a time, in order.
- Within a shot, block the key poses first and check them as stills (`--sheet` at the key times). Add the motion between them once they read.
-
-```js
-// src/scenes/my_video.js
-(() => {
-  function park(t, lt, dur) {                        // t = video time, lt = time in this shot, dur = shot length
-    camBegin(960 + 20 * Math.sin(lt * .6), 540, 1 + .02 * lt);   // slow drift and push: the camera is never dead
-    paint(rectPts(-200, -200, W + 400, H + 400), { wash: PAL.sky, ink: null });           // background
-    paint(ellPts(960, 1150, 1400, 380, 40, 2), { wash: PAL.sap, ink: PAL.ink, sw: 1 });   // ground
-    const mood = emotions(lt, [[0, 'bored'], [1.2, 'surprised'], [1.7, 'excited']]);      // acted changes
-    const hop = jump(lt, 2.2, 2.7, 3);                                                    // add poses that share fields
-    clawd(960, 860, 26, { ...mood, dy: mood.dy + hop.dy, sq: mood.sq + hop.sq });
-    const at = toScreen(960, 860 - 4 * 26);          // Clawd's screen position, for the iris
-    camEnd();
-    if (lt < .45) iris(...at, lerp(0, 1500, easeIn(lt / .45)));            // transition in
-    if (lt > dur - .3) brushWipe((lt - (dur - .3)) / .6);                 // transition out (next shot finishes it)
-  }
-  shots([[0, park] /*, [3.5, nextShot], ... */]);
-})();
-```
-
-### 3. Look at it: the review loop
-
-You can't see motion by reading code. Render and look at every shot, several times, at three zoom levels:
-
-```bash
-# contact sheet: the shape of the whole piece (every shot's first, middle and last frames)
-node render.mjs --sheet=0.1,0.8,1.6,2.4,3.1,3.9 --cols=6 --w=320 --out=out/check/sheet.jpg
-# strip: EVERY frame of a moment (turns, takes, jumps, throws, transitions)
-node render.mjs --strip=2.1:2.6 --cols=6 --w=320 --out=out/check/strip.jpg
-# crop: full-resolution detail (faces, hands, contacts, glows); crop=x,y,w,h in frame pixels
-node render.mjs --sheet=2.3,2.4 --crop=760,420,500,400 --w=500 --out=out/check/face.jpg
-# crop-at: the same, following a WORLD point through each frame's camera (a foot or a prop on a moving shot);
-# x,y in world pixels (or an expression evaluated in the page), w,h in frame pixels
-node render.mjs --strip=2.1:2.6 --crop-at=960,700,500,400 --out=out/check/feet.jpg
-```
-
-Open each image and actually look at it. Check:
-
- **Read:** is the event of each shot clear from its sheet alone? Is Clawd big enough, and does Clawd separate from the background?
- **Timing.** You can't judge timing from single frames, so read it like a viewer:
-  - Render the shot as a sheet at a fixed step (every 0.1–0.15 s) and read it in order.
-  - At each frame ask: where is the viewer looking right now, and do they understand it yet?
-  - Count the frames each read gets (24 frames = 1 s). A read that flashes by in a few frames, or shares its frames with another read, will be missed.
-  - After each important moment, is there time to take it in before the next thing starts?
- **Motion:** in strips, does every move have anticipation and follow-through? Are there any pops, jumps or snaps between frames? Do the parts move at different times, or all at once? Is anything moving at a constant speed, or mirrored left and right? Are the poses pushed far enough to read?
- **Boil:** in a strip, each pair of frames that share a boil drawing should match except where something moves. Anything still that changes every frame needs its own `boilSeed()`.
- **Contacts:** do feet touch the ground? Do held things touch the arm tips? Do thrown things leave from the hand?
- **Transitions:** check the first and last 0.5 s of every shot and every seam. Does it open and close with a transition?
- **Rules:** is there any text? Is there any 3D? Is there any dead stretch where nothing is happening?
- **Colour:** any muddy glows (use `glow()`), pure black or pure white?
-
-Fix what you find, then look again. **Budget:** at least one sheet per shot, a strip for every key motion and transition, and a crop for every face that carries the story. Contact sheets run about 0.1–1 s per frame, so this is cheap: don't skip it.
-
-### 4. Render
-
-```bash
-node render.mjs --clip --out=out/video.mp4                      # the whole video, straight to MP4
-node render.mjs --frames --workers=4                            # or: parallel + resumable JPEG frames into out/frames …
-node render.mjs --encode --out=out/video.mp4                    # … then encode them

-
-### Frames are pure functions of time
-
- **Frames render in parallel and out of order.** A shot is `fn(t, lt, dur)` and must draw the same frame for the same `t`, every time. No state carried between frames, no counters, no `Math.random()`, no physics that integrates frame by frame. Compute everything from `t`, in closed form (the helpers below do this for you).
- Randomness: `hash(i)` for stable per-object values, and `jit(a)`/`random()` for boil (they change 12 times a second).
- **Seed each element with `boilSeed(key)`.** Each boil drawing holds for two frames, so anything that isn't moving must draw the same in both. But a moving thing uses a different amount of randomness each frame, which shifts the stream for everything drawn after it, and all of that re-boils every frame and looks jittery.
-  - `boilSeed(key)` restarts the stream from the boil frame and a key that stays the same every frame (any string or number, unique within the frame).
-  - Call it before each separate element: each background layer, prop and effect.
-  - `clawd()` seeds itself and each of its parts, then reseeds when it's done, so nothing drawn after it depends on its pose. Its key is its call order; set `boilKey` if characters come and go mid-shot.
- **Each shot paints the whole frame,** background included. The paper texture is under everything and the grain is multiplied over the top, so leaving paper showing is a valid look.
- **Canvas:** 1920×1080, origin top-left, y down.
- `LOOPS.name = t => {...}; LOOPS.name.len = 4;` makes a standalone loop (tests, GIFs, sheets), rendered with `--loop=name`.
-
-### Painting
-
-`paint(pts, o)` paints one shape from a point list `[[x, y], ...]`:
-
-| option | meaning |
-|---|---|
-| `wash, washOp` | flat colour (opacity 0–255, default 255). For characters, props, anything solid. |
-| `fill, fillOp, bleed, tex, border` | watercolour fill with bleeding edges and pigment texture. For skies, hills, shading and shadows. `bleed` ~.05–.3, `tex` ~.3–.9. |
-| `hatch: { d, a, o, b, c, w }` | hatching (distance, angle, `{rand, gradient}`, brush e.g. `'charcoal'`/`'HB'`, colour, weight). Texture, sparingly. |
-| `ink, sw, br` | outline colour (default `PAL.ink`), weight (~.4–2), brush. **`ink: null` means no outline.** |
-| `curv` | 0–1: smooth the outline through the points. |
-
- **Lines:** `inkLine(pts, sw, colour, brush = 'ink', curvature)`. The kit's brushes are `'ink'`, `'inkfine'` and `'dry'` (bristly). p5.brush's built-ins also work: `'2B'`, `'HB'`, `'charcoal'`, `'marker'`, `'pen'`, `'cpencil'`, `'rotring'`, `'spray'`.
- **Shapes:**
-  - `rectPts(x, y, w, h, jitter)`
-  - `ellPts(cx, cy, rx, ry, n, jitter, rot)`
-  - `rrPts(x, y, w, h, r, jitter)`: a rounded rectangle
-  - `starPts(cx, cy, r, inner, n, rot)`
-  - `heartPts(cx, cy, r)`
-  - `through(P)`: a smooth curve through the points
-  - `ribbon(P, w0, w1)`: a tapered ribbon along a path, as one outline. Use it for tails, trails, vines and noodly arms.
- **One shape, one outline.** Build a creature or prop from as few outlines as you can, so it doesn't look like glued-on stickers: a tail is one `ribbon`, not five circles.
- **Light:** `glow(x, y, r, colour, a)`. It's additive, so it stays warm on dark grounds and barely shows on light ones (as real light would). Draw it before the things that sit in front of the light.
- **Palette** `PAL`: `paper, ink, clay, clayDk, clayLt, night, indigo, rose, ochre, sap, teal, violet, cream, sky`. `mixCol(a, b, k)` mixes two hex colours in RGB. Any hex colour works: pick a small palette per video.
- **p5.brush quirks:**
-  - Colours mix like pigment: yellow over blue makes green. Layer light colours over dark ones with a full-opacity `wash`, or use `glow()`.
-  - `wash` at 255 is exact colour; lower opacities mix.
-  - Strokes drawn far from the origin under a zoomed camera collapse: from zoom ~2, an outline or a line at large
-    world coordinates leaves only a dot at its first vertex. `paint()` and `inkLine()` draw each shape around its own
-    centre, which avoids it. A shape much bigger than the canvas can still lose its outline: draw long edges as
-    `inkLine`s no bigger than the canvas.
-  - Outline weight is in world units, so it grows with the camera's zoom: a fine outline on a small shape becomes a
-    dark blob in a close-up. Scale `sw` down with the zoom for small shapes.
-  - A NaN in a point list throws `Failed to construct 'OffscreenCanvas': Value is not of type 'unsigned long'`, with
-    a stack pointing at your scene rather than the NaN. Guard geometry that can degenerate (`Math.acos` of a ratio > 1).
-  - p5 `push()/pop()/translate()/rotate()/scale()` work with all brush calls.
-  - Cost is the number of `fill` shapes and strokes: hundreds are fine, thousands are not. Aim for ≤ 1.5 s per frame. The render log prints ms/frame.
-  - Some scenes make p5.brush log five `WebGL: INVALID_OPERATION ... not from the associated program` warnings once per page. They're harmless (frames come out identical). Any other page error is real.
-
-### Time and motion (all pure functions of t)
-
- **Progress and keys:**
-  - `seg(t, a, b)`: 0..1 progress through [a, b]
-  - `kf(t, [[t0, v0], [t1, v1], ...], ease)`: keyframes; values may be arrays
-  - `lerp`, `clamp`, `frac`, `wob(t, freq, phase)`, `TAU`
- **Easing:** `ease`, `easeIn`, `easeOut`, `backOut` (overshoot) and `elasticOut`.
- **Rhythm:** `BEAT` (seconds per beat), `bpOf(t)` (beat position), `beatN(t)` (beat number), and `pulse(t, k)` / `pulse2(t, k)`, which are 1 on each beat (or eighth) and then decay.
- **Acting:**
-  - `jump(t, t0, t1, h)`: crouch, stretch, arc and squash-land. Returns `{dy, sq}`.
-  - `take(t, t0, amt)`: a surprise take, returns `{sq, dy}`.
-  - `stroll(t, t0, t1, x0, x1, u)`: an eased walk. Returns `{x, walk, view, flip, dy}`.
-  - `spring(t, t0, k, w)`: a damped wobble after an event, for settles and follow-through.
-  - `ring(t, [t0, t1, ...])`: one `spring` kick per event time.
-  - `arcPt(p0, p1, h, k)`: a point on a thrown arc.
-  - `onTwos(t)`: holds each drawing for two frames. Wrap a shot's `t` in it for a snappier, hand-drawn feel.
- **Camera:**
-  - `camBegin(cx, cy, zoom, rot)` … `camEnd()`: world point (cx, cy) lands at screen centre. One level only; always pair them.
-  - `toScreen(x, y)`: world → screen while a camera is active. Use it to aim an iris at a character.
-  - `shakeXY(t, amount)`: [dx, dy] to add to the camera on impacts.
- **Full-frame effects** (screen space, after `camEnd()`):
-  - `brushWipe(p, [c1, c2])`: fat strokes cover the frame (p 0 → .5) and then drag off (.5 → 1). Cut under full cover. Its comment in timeline.js shows the two calls.
-  - `iris(cx, cy, r, colour)` and `irisShape(pts, colour)`: shaped reveals.
-  - `flash(k, colour)`: a full-frame flash.
- **Lettering** (only if you must, see "No text"):
-  - `letter(txt, x, y, size, colour, {pop, rot, alpha, screen})`
-  - `sfx(txt, x, y, size, colour, age)`
-  - Both are composited at `flushLetters()`, after the shot. If a wipe or iris must cover them, call it yourself first.

-## Clawd
-
-Clawd is the Claude Code mascot: a terracotta block (`PAL.clay`), 10 units wide and 6 tall, with four stubby legs, two little arm nubs and two tall slit eyes. There's no mouth at rest. It's drawn in flat wash with an ink outline and boils like everything else. That's the default design, not a rule: change it if the idea needs it. Within one video, though, keep every character on model, with the same shape and features in every shot.
-
-```js
-clawd(x, y, u, options)   // (x, y) = ground point between the feet; u = size unit
-```
-
-**Sizes:** Clawd is 10u × 8u (legs included).
-
-| shot | u | on screen |
-|---|---|---|
-| wide | 10–16 | small in the landscape |
-| medium | 20–28 | the usual acting size |
-| close-up | 40–70 | face acting |
-| extreme close-up | 90+ | camera pushed in on the eyes |
-
-### Options
-
-| group | options |
-|---|---|
-| pose | `dx`, `dy` (in u; −dy = up), `sq` (squash; negative stretches), `rot` (pivots at the feet), `flip`, `sx`, `sy`, `aL`, `aR` (arm angle: 0 = straight out, + = up, − = down; ±1.5 is vertical), `walk` (leg phase), `noLegs`, `noShadow` |
-| view | `view`: front, q, side, qback, back. `smear` 0..1 + `smearDir` ±1 (0 = both sides) for fast moves |
-| face | `eyes`, `mouth`, `lookX`/`lookY` (−1..1), `squint` 0..1, `blush` 0..1, `gloom` 0..1, `lid` 0..1, `seed` (blink timing) |
-| colour | `tint` (pale, flush, blue, rosy, green, gold, or any hex) + `tintK`, or `col`/`dk`/`lt` directly |
-| extras | `hat`, `emote` + `emoteK` (0..1 pop) + `emoteAge`, `draw(u, sw)`, `armL(u, sw)`, `armR(u, sw)` |
-| boil | `boilKey`: a stable id for its boil seeds (default: call order) |
-
-Options compose by spreading: `clawd(x, y, u, { ...feel('happy', t), ...turn(t, 1, 1.15, 0, .25), hat: 'party' })`. Later spreads win, so put the emotion first and the pose after it. If both an emotion and a pose move the same field (`dy`, `sq`), add them together rather than letting one silently replace the other.
-
-### Views and turns
-
-These are drawn key views. Every view faces screen-right; add `flip: true` to face left.
-
-| view | what you see |
-|---|---|
-| `front` | the face, both arms, four legs |
-| `q` | 3/4: the face shifted toward the heading, the side face as a darker strip behind it |
-| `side` | profile: one eye near the leading edge, one arm |
-| `qback` | 3/4 from behind: no face |
-| `back` | no face |
-
- **Turn with `turn(t, t0, t1, a0, a1)`.** Headings are in turns: 0 = front, .25 = facing right, .5 = back, −.25 = facing left. It steps through the key views over 0.12–0.25 s with smears, like a drawn turn. For a single heading, use `spinView(a)`.
- **Walks across the screen** read best in `side` view with `walk` driving the legs. `stroll()` gives `q`; override it with `view: 'side'` for a trot.
- **Facing right, `aL` is the near arm** (drawn in front of the body), and the far arm is behind and darker.
-
-### Emotions
-
-31 emotions. Each is a face, a colour and a way of moving, all locked to the beat. `feel(name, t, over)` returns all of it at time t:
-
-```js
-clawd(x, y, u, feel('happy', t));                                   // one emotion, alive
-clawd(x, y, u, feel('sad', t, { view: 'q', lookX: -1 }));             // with overrides
-clawd(x, y, u, emotions(t, [[0, 'sleepy'], [1.9, 'surprised', { lookX: .8 }], [2.5, 'idea']]));   // acted changes
-```
-
-| family | emotions |
-|---|---|
-| joy | happy, excited, laugh, love, proud, starstruck, playful, hopeful, relieved |
-| sly | smug, cool, mischief, suspicious |
-| low | sad, cry, bored, sleepy, ko |
-| hot | angry, furious (the lunchbox lid opens), determined, disgusted |
-| alarm | scared, nervous, surprised, confused, dizzy |
-| mind | neutral, thinking, idea, shy |
-
- **`emotions(t, keys)`** is how moods change in a shot. Around each key it squints and squashes just before the change (anticipation), swaps the face under the squint, and fires a take sized to the new emotion. The body then settles into the new motion with overshoot, colour cross-fades and the new emote pops in.
-  - `emotions(t, keys, { take: .5 })` scales every take.
-  - The third element of a key overrides fields for that stretch (e.g. `{ lookX: .8, emote: 'music' }`).
- To make a new emotion, add an entry to `EMO` in clawd.js. It needs eyes, mouth, optional tint/blush/gloom/lid/emote, `take` (reaction size) and `body(t)` (its idle motion, locked to the beat through `_b(t)`).
-
-### Parts
-
- **Eyes:** normal, look, wide, happy, closed, sleepy, wink, narrow, angry, determined, sad, teary, cry, squeeze, shine, scared, blank, spark, red, heart, x, swirl, dot, shades.
-  - A pair gives mismatched eyes, e.g. `['narrow', 'wide']`.
-  - `lookX`/`lookY` aim the pupils, and `squint` closes the eyes from any shape.
- **Mouths:** o, O, smile, grin, flat, wobble, cat, frown, smirk, laugh, open, wail, teeth, tongue, pout, yawn. Use `null` for none (Clawd's resting face).
- **Lunchbox lid:** `lid` 0..1 hinges the top of the body open, with teeth pointing into the mouth. It's for fury, chomping and shouting, in the front view only.
- **Hats:** party, hard, crown, halo, wizard, hood, top, fedora, band, sweatband, beanie, bow, flower, headphones, cat (ears and whiskers). Face pieces: masq, mask, bowtie.
- **Emotes** are painted marks that pop in by the head: `!` `?` `!!` `!?` zzz, sweat, spark, heart, hearts, anger, steam, bulb, dots, scribble, music, swirl, stars, cloud.
-  - `emoteK` is the 0..1 pop and `emoteAge` drives the looping ones; `emotions()` sets both.
-  - `emote(kind, x, y, s, k, age)` draws one anywhere, for example over a prop.
- **Body colour:**
-  - `tint` shifts it with the mood: pale (fear), flush (anger), blue (sadness), rosy (love), green (disgust), gold (pride).
-  - `gloom` adds a dark forehead with hanging lines, and `blush` adds cheeks (hatched when above .6).
-
-### Hooks: props and accessories
-
- **`draw(u, sw)`** paints in body-local space, on top of everything else on the body (face, hat, near arm). It squashes, flips and rotates with Clawd. Front-view coordinates:
-  - the body spans x −5u..5u and y −8u..−2u
-  - the eyes are at (±2.5u, −6u)
-  - the mouth is near (0, −4.3u)
- **`armL(u, sw)` / `armR(u, sw)`** are called at the arm tip, in arm space (+x runs outward along the arm), so a held prop just draws around (0, 0) and follows the arm automatically:
-
-```js
-clawd(x, y, 24, { ...feel('proud', t), aR: 1.2, armR: (u, sw) => paint(starPts(u * .8, 0, u * 1.4, .5, 5), { wash: '#FFE27A', sw }) });
-```
-
- Anything the arms can't carry, like a big object overhead, is drawn separately at a point computed from the same pose. The demo's star does this. Make sure it touches: check it with a crop.
-
-### Dances
-
-`move(style, t, seed)` returns beat-locked pose offsets. The styles are bounce, hop, roof (arms up), sway, spin (a drawn spin through the key views once a bar), wave, walk, run, idle, stomp and shimmy. `mix` changes style every two bars. `dancer(x, y, u, style, t, extra)` is `clawd` + `move`. You can combine a dance with a face: `{ ...move('bounce', t), eyes: 'happy', mouth: 'grin' }`.
-
---
-
-## Music (optional)
-
-The kit doesn't need music, but it's built for it:
-
-1. Set `bpm` to the song's tempo in [src/config.js](src/config.js), and set `offset` to the time of its first downbeat in seconds. Every idle, dance and `pulse()` then locks to the song.
-2. Put the audio in `assets/` and set `PROJECT.audio` (or pass `--audio=`). `--clip` and `--encode` mux it in.
-3. Land hits, cuts and takes on beats (`beatN`, `pulse`). Cut on bar lines for big changes, and give each musical phrase its own visual.
-4. **Lyrics are not text.** Don't put words on screen. Act the meaning of a line instead.
-
-## Common failures
-
-These are the things that make a Clawd video look generated. Check your storyboard and sheets against them:
-
- signs, captions, labels or speech bubbles with words
- Clawd standing still and smiling while nothing happens
- everything moving at one brisk speed, with events stacked on top of each other and no holds
- moments that are over before the viewer understands them
- a tiny Clawd in a big empty landscape for the whole video
- faces that snap from one expression to another
- mechanical motion: linear moves, every part moving at once, both arms or several characters in sync
- timid poses and takes that barely read
- jittery linework: still things re-boiling every frame because something moving before them shifted the random stream (`boilSeed`)
- hard cuts everywhere, or a video that just starts and stops
- 3D rotation, perspective boxes or projected turns
- plain p5 shapes, gradients or digital glows mixed into the paint (use `paint`/`inkLine`/`glow`)
- muddy green-grey glows from painting yellow over blue
- props floating near a hand instead of touching it
- every shot a different world with nothing linking them
-
-## About the demo
-
-[src/scenes/demo.js](src/scenes/demo.js) ("The fallen star") exists to show the kit working: an acted emotion timeline, a drawn turn, a trot, a pickup, a throw on an arc, `glow`, a brush wipe and an iris in and out. **It's one idea, not a template.** Don't reuse its story, night sky, hills, star or shot structure. Start from the prompt and your own storyboard, and replace its script tag in `studio.html` with yours.
-
-### Worked example: how the demo times its ending
-
-This shows rule 4 applied to one shot of one video. The reads, the numbers and the way it ends are specific to this story; yours will be different. Read it for the reasoning, not the numbers. It's the demo's last shot, from the throw on, in video time:
-
-| time | read | why it's timed this way |
-|---|---|---|
-| 6.95–7.1 | wind-up and throw | fast motion; it reads because the wind-up anticipates it |
-| 7.1–7.9 | the star flies home | long enough for the eye to follow it from Clawd to the top of the frame; the camera eases back to give it sky |
-| 7.9–8.35 | it arrives: a flare, a sparkle, the sky twinkles | the payoff. Clawd only watches, so nothing competes with it |
-| 8.35–8.95 | Clawd falls in love | the reaction starts only after the viewer has seen the cause |
-| 8.95–9.4 | Clawd waves goodbye | a new action, on its own |
-| 9.4–9.8 | the star twinkles back | the answer to the wave |
-| 9.8–11.0 | iris to Clawd, hold, shut | the last read gets time to land before the video ends |
-
-The first version packed all of this into about 1.3 s, and nobody could tell what had happened.

-# Claude Animation Base
-
-This is a small starter kit with code, instructions and assets for animating a character in [p5.js](https://p5js.org) and [p5.brush](https://github.com/acamposuribe/p5.brush) with Claude Opus 5.5. It's based on the code from the music video [I'm Upping My P(doom)](https://github.com/JohnHeibel/PDoomVideo) and an analysis of what the model did and didn't do well. I highly recommend playing around with your prompting: make it give you the storyboard before coding, give it very broad instructions, try being very specific, ask for subagents, and try a bunch of other fun ways of testing the model's capabilities. In my testing, it can do a lot with very little, but it's also quite accurate when you give it more requirements. Also try asking the model to swap out the character or make new emotions or costumes, give it your own reference images, and try many other fun things like that. I've found that the reasoning level corresponds to how "extravagant" and detail-oriented the model makes the scene. All test videos were generated with Opus 5.5 on xhigh reasoning in Claude Code.
-
-![Clawd's emotions, animated](docs/emotions.webp)
-
-## Make a video
-
-Clone it, open it in Claude Code (or any coding agent) and ask for what you want:
-
-> Read ANIMATION_GUIDE.md, then make a 15-second video of Clawd trying to catch a butterfly.
-
-The model storyboards first, builds shot by shot, renders contact sheets to check its own work, and writes `out/video.mp4`. [ANIMATION_GUIDE.md](ANIMATION_GUIDE.md) holds the rules it follows: handmade, alive, one piece, no text, transitions always, something happens in every scene, and a solid medium of brush strokes, flat 2D and boiling linework. It also covers timing for the viewer and the core principles of character animation.
-
-## Run it yourself
-
-You need Node.js, Google Chrome and ffmpeg.
-
-Without a dedicated GPU, p5.brush's watercolour fills make render times fairly slow, measured in seconds per frame. If you're running on integrated graphics, I recommend asking the model to avoid those fills and replace them with something else appropriate. (I love the look of the watercolours, though.)
-
-```bash
-npm install
-node render.mjs --clip --out=out/video.mp4
-```
-
-That renders the 11-second demo in [src/scenes/demo.js](src/scenes/demo.js). Open [studio.html](studio.html) in Chrome to scrub through it. Add `?loop=emotions` or `?loop=views` to see the model sheets. If Chrome isn't in a standard location, pass `--chrome=<path>` or set `CHROME_PATH`.
-
-On Linux, `render.mjs` starts Chrome with `--no-sandbox` (Ubuntu 23.10+ blocks Chrome's sandbox in headless use) and also finds a Chromium installed by Playwright. With no GPU at all, add `--soft-gl` to render WebGL in software: slow on watercolour fills, but it works. On a headless Linux machine with an NVIDIA GPU (a cloud or cluster node), add `--gpu-angle=gl-egl` (or `vulkan`); `node gpu_probe.mjs <chrome path>` shows which renderer each set of flags gets.
