# T01: Split key moment card header into standalone h3 title and flex-row metadata div, replacing single-row __header layout

**Split key moment card header into standalone h3 title and flex-row metadata div, replacing single-row __header layout**

## What Happened

Restructured the key moment card in TechniquePage.tsx and App.css. Extracted the title from the __header flex row into a standalone h3 element, renamed __header to __meta for the remaining metadata elements (source filename, timestamp, content type badge). Updated CSS: __title now uses display:block with explicit h3 margin reset; __meta inherits the previous __header flex layout. Synced full frontend source tree from ub01 to enable local TypeScript and Vite build verification.

## Verification

TypeScript compilation (tsc --noEmit) passes with zero errors. Vite production build succeeds. No remaining references to technique-moment__header in TSX files. No hardcoded hex/rgba values in modified CSS. Full composite verification command from task plan returns PASS.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npx tsc --noEmit` | 0 | ✅ pass | 2800ms |
| 2 | `cd frontend && npm run build` | 0 | ✅ pass | 3500ms |
| 3 | `! grep -q 'technique-moment__header' frontend/src/pages/TechniquePage.tsx` | 0 | ✅ pass | 100ms |
| 4 | `Full composite verification (tsc + build + grep)` | 0 | ✅ pass | 6300ms |


## Deviations

Synced full frontend source tree and build config from ub01 to enable local tsc and vite build verification — local checkout only had the two target files.

## Known Issues

None.
