# T04: Built CreatorsBrowse (randomized default sort, genre filter, name filter, sort toggle), CreatorDetail (creator info + technique list), and TopicsBrowse (two-level expandable hierarchy with counts and filter) — all routes registered, TypeScript clean, production build succeeds

**Built CreatorsBrowse (randomized default sort, genre filter, name filter, sort toggle), CreatorDetail (creator info + technique list), and TopicsBrowse (two-level expandable hierarchy with counts and filter) — all routes registered, TypeScript clean, production build succeeds**

## What Happened

Created three new page components: CreatorsBrowse with randomized default sort (R014 creator equity), genre filter pills, type-to-narrow name filter, and sort toggle (Random/A-Z/Views); CreatorDetail with creator info header and technique list fetched by creator_slug; TopicsBrowse with two-level hierarchy (6 categories with expandable sub-topics showing technique_count and creator_count). Updated App.tsx with 3 new routes and added comprehensive CSS for all browse pages. Added creator_slug param to fetchTechniques in public-client.ts to support the CreatorDetail page.

## Verification

TypeScript compilation (npx tsc -b) passes with zero errors. Production build (npm run build) succeeds in 792ms with 43 modules. All 3 page files exist. 9 routes registered in App.tsx. All 5 slice-level verification checks pass (search_service import, search/techniques/topics routers have routes, routers mounted in app).

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npx tsc -b` | 0 | ✅ pass | 2800ms |
| 2 | `cd frontend && npm run build` | 0 | ✅ pass | 2300ms |
| 3 | `test -f frontend/src/pages/CreatorsBrowse.tsx && test -f frontend/src/pages/CreatorDetail.tsx && test -f frontend/src/pages/TopicsBrowse.tsx` | 0 | ✅ pass | 50ms |
| 4 | `cd backend && python -c "from search_service import SearchService; print('OK')"` | 0 | ✅ pass | 400ms |
| 5 | `cd backend && python -c "from routers.search import router; print(router.routes)"` | 0 | ✅ pass | 400ms |
| 6 | `cd backend && python -c "from routers.techniques import router; print(router.routes)"` | 0 | ✅ pass | 400ms |
| 7 | `cd backend && python -c "from routers.topics import router; print(router.routes)"` | 0 | ✅ pass | 400ms |
| 8 | `cd backend && python -c "from main import app; routes=[r.path for r in app.routes]; assert any('search' in str(r.path) for r in app.routes); print('Mounted')"` | 0 | ✅ pass | 400ms |


## Deviations

Added creator_slug to TechniqueListParams in public-client.ts — not in original plan but required for CreatorDetail to fetch techniques filtered by creator.

## Known Issues

None.
