# S04: Admin Profile Editing + Mobile Polish

**Added inline admin editing for creator bio/social links and 480px responsive overrides for the creator detail page.**

## What Happened

Two tasks delivered the slice goal. T01 added an `updateCreatorProfile()` API client function to `public-client.ts` and a full inline edit mode to `CreatorDetail.tsx` — Edit button in the hero, bio textarea pre-filled with current content, social links editor with platform dropdown + URL input rows (add/remove), save/cancel with optimistic local state update, saving indicator, and error display. T02 added a `@media (max-width: 480px)` block with 15 CSS rule overrides targeting stats bar, topic pills, hero section, featured card, technique grid, social icons, genre pills, techniques header, and the new edit form — ensuring the page renders cleanly at 375px (iPhone SE).

## Verification

All slice plan verification checks pass: `tsc --noEmit` exits 0, `npm run build` exits 0, `grep updateCreatorProfile` confirms API client export, `grep editMode` confirms edit state in CreatorDetail, `grep 480px` confirms narrow breakpoint in App.css.
