**Part 4 complete.** You now have all 4 deliverable files:

| File | What it does |
|------|-------------|
| `manifest.json` | PWA identity + icon + display mode |
| `sw.js` | Offline-first caching, cache-first for assets, nav fallback |
| `vercel.json` | SPA rewrite rules + security headers + long-term asset caching |
| CSS block | Styles for all panels + all 5 council features + quiz, ncert, graph, revision, scheme, performance |
