+# IT Support Site: PRD (plan)
+
+Restaurant analogy: the FAQ database is the **kitchen's recipe book**. The website is the **dining room**.
+
+## Core features
+1. Cinematic hero: looping video, glass buttons (exactly as specified)
+2. Search bar in the hero: type a problem, get matching answers
+3. Category chips: browse the 11 topics (Access, Network, Hardware...)
+4. FAQ answer cards: question, answer, optional "official guide" link
+5. Footer social icons
+
+## Phased roadmap
+- **Phase 1 – Food stand (TODAY):** hero + search + categories + 87 FAQs from the database, baked in as a JSON file. No server.
+- **Phase 2 – Small restaurant:** "Was this helpful?" votes, "Contact IT" ticket form, shareable links per question.
+- **Phase 3 – Full restaurant:** small back-of-house server + real database, staff login, admin page to edit FAQs, ticket tracking.
+
+## Test ladder
+1. Page loads, no console errors  2. Buttons/search work  3. Real data/links work  4. Security (no raw HTML injection, safe links)
