-- [ ] **T02: Mobile responsive polish for creator detail page at 375px** — Add CSS media query fixes so the creator detail page renders cleanly at 375px (iPhone SE width).

+
+**Added 480px media query with 15 rule overrides for stats bar, featured card, technique grid, social icons, genre pills, and edit form on the creator detail page**
+
+## What Happened
+
+Read existing responsive breakpoints (640px hero stacking, 768px admin layout) and full creator-detail class names. Added a @media (max-width: 480px) block with targeted overrides for stats bar (smaller font, tighter gap), topic pills (compact badges), hero (smaller name/bio, tighter gaps), featured card (reduced padding/text), techniques header (flex-wrap for sort dropdown), technique cards (reduced padding), and edit form (full-width stacked inputs). All CSS-only — no component changes needed.
+
+## Verification
+
+TypeScript check and Vite build both pass. grep confirms 480px breakpoint exists. Slice-level checks for updateCreatorProfile and editMode also pass.
