# T03: Built complete admin review queue UI: queue list page with stats bar, status filter tabs, pagination, mode toggle; moment detail page with approve/reject/edit/split/merge actions and modal dialogs; reusable StatusBadge and ModeToggle components

**Built complete admin review queue UI: queue list page with stats bar, status filter tabs, pagination, mode toggle; moment detail page with approve/reject/edit/split/merge actions and modal dialogs; reusable StatusBadge and ModeToggle components**

## What Happened

Replaced the placeholder ReviewQueue page with a full-featured admin queue page: stats bar showing counts per status, 5 filter tabs that re-fetch data on click, paginated moment list with Previous/Next navigation, queue cards with title/summary/creator/video/time/status badge, and empty state. Added ModeToggle to queue page header and global app header with green/amber dot indicator. Built MomentDetail page with complete moment data display, action buttons (Approve/Reject navigate back, Edit toggles inline editing, Split opens modal with timestamp validation, Merge opens modal with same-video moment dropdown), loading/error states. Created reusable StatusBadge and ModeToggle components. Updated App.tsx and wrote comprehensive CSS covering all UI elements with responsive layout.

## Verification

Frontend build succeeds with zero TypeScript errors. All task-level grep checks pass (StatusBadge/ModeToggle integrated in ReviewQueue, all action names present in MomentDetail). All slice-level backend tests pass (24/24 review tests, 40/40 full suite, 9 routes registered).

## Deviations

MomentDetail uses fetchQueue with limit=500 to find individual moment since there's no dedicated single-moment GET endpoint. Works for single-admin tool scope.

## Known Issues

None.
