# T01: Created AdminDropdown component with click-outside/Escape close, wired into App.tsx header replacing 3 admin links + ModeToggle, added dropdown CSS using existing theme tokens

**Created AdminDropdown component with click-outside/Escape close, wired into App.tsx header replacing 3 admin links + ModeToggle, added dropdown CSS using existing theme tokens**

## What Happened

Created AdminDropdown.tsx with useState toggle, useRef click-outside listener, Escape handler, accessible button trigger (aria-expanded, aria-haspopup), and role=menu div with 3 Link menuitem elements. Updated App.tsx to import AdminDropdown instead of ModeToggle, replaced 3 admin Link elements and ModeToggle JSX with single AdminDropdown component. Appended BEM-style dropdown CSS to App.css using existing theme custom properties. ModeToggle preserved — still imported by ReviewQueue.tsx.

## Verification

TypeScript check (tsc --noEmit) passed with zero errors. Vite production build succeeded — 47 modules transformed, built in 778ms. Both slice-level verification commands pass.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npx tsc --noEmit` | 0 | ✅ pass | 3000ms |
| 2 | `cd frontend && npx vite build` | 0 | ✅ pass | 4400ms |
