# S01: Frontend Schema Sync + Hero Section

**Synced CreatorDetailResponse with 7 new backend fields, eliminated redundant fetchTechniques call, and replaced compact header with a full hero section (96px avatar, 2rem name, bio, genre pills, separated stats bar).**

## What Happened

This slice delivered two changes to the Creator detail page:

**T01 — Schema Sync:** Extended `CreatorDetailResponse` in `public-client.ts` with all backend `CreatorDetail` fields: `bio`, `social_links`, `featured`, `avatar_url`, `technique_count`, `techniques` (via new `CreatorTechniqueItem` interface), and `genre_breakdown`. Removed the separate `fetchTechniques()` API call from `CreatorDetail.tsx` — the detail endpoint already returns the techniques array, so the redundant network request was eliminated. Technique sorting is now client-side on the already-fetched array. Topic pills now use `genre_breakdown` from the backend instead of computing from individual technique tags.

**T02 — Hero Section:** Replaced the old `creator-detail__header` block with a new `creator-hero` layout. Features a 96px `CreatorAvatar` (using `avatar_url`), prominent 2rem/800-weight name, conditional bio paragraph (hidden when null), and genre pills using the existing `.pill` class. Stats moved to a dedicated bar below the hero with a border separator. CSS includes responsive behavior — vertical stacking with centered avatar below 768px. Old unused `.creator-detail__header` rules removed.

Minor deviation: T02 had to remove an unused `CreatorTechniqueItem` import left by T01 that caused `tsc -b` (used by the build step) to fail with TS6133. Clean coordination issue, fixed inline.

## Verification

- `npx tsc --noEmit`: zero type errors (exit 0)
- `npm run build`: clean production build — 58 modules, zero warnings (exit 0)
- Schema fields verified present: bio, social_links, featured, avatar_url, technique_count, techniques, genre_breakdown
- Hero component classes verified in CreatorDetail.tsx: creator-hero, creator-hero__info, creator-hero__name, creator-hero__bio, creator-hero__genres
- Hero CSS verified in App.css with responsive mobile stacking
- fetchTechniques: zero references remaining in CreatorDetail.tsx
