# T01: Fix key moment card CSS overflow for titles, filenames, and meta row

Apply four CSS property changes to `frontend/src/App.css` to prevent key moment card text from overflowing the sidebar bounds.

The key moment cards live in the technique page sidebar (22rem wide, ~20rem inner after padding). Long filenames in `.technique-moment__source` have `max-width: 20rem` which can exceed the actual container. Titles have no wrapping control. The card container has no overflow clip.

## Steps

1. Read `frontend/src/App.css` lines ~1512–1555 (the `.technique-moment*` rules)
2. Add `overflow: hidden` to `.technique-moment` (the card container) — clips any child that escapes card bounds
3. Add `word-break: break-word` to `.technique-moment__title` — long titles wrap instead of overflowing (wrapping preferred over truncation since titles are meaningful)
4. Change `max-width: 20rem` to `max-width: 100%` on `.technique-moment__source` — respects actual container width instead of a fixed value that may exceed the sidebar
5. Add `min-width: 0` to `.technique-moment__meta` — required for flex child truncation to work reliably in a flex container
6. Run `cd frontend && npm run build` to verify zero errors

## Must-Haves

- [ ] `.technique-moment` has `overflow: hidden`
- [ ] `.technique-moment__title` has `word-break: break-word`
- [ ] `.technique-moment__source` uses `max-width: 100%` not `max-width: 20rem`
- [ ] `.technique-moment__meta` has `min-width: 0`
- [ ] Frontend builds with zero errors

## Verification

- `cd frontend && npm run build` passes
- `grep 'overflow: hidden' frontend/src/App.css` shows the `.technique-moment` rule
- `grep 'word-break: break-word' frontend/src/App.css` shows the title rule
- `grep 'max-width: 100%' frontend/src/App.css` shows the source rule

## Inputs

- `frontend/src/App.css` — existing CSS with `.technique-moment*` rules around lines 1512–1555

## Expected Output

- `frontend/src/App.css` — modified with four overflow-fix properties added/changed

## Inputs

- `frontend/src/App.css`

## Expected Output

- `frontend/src/App.css`

## Verification

cd frontend && npm run build 2>&1 | tail -5 && echo '---' && grep -A2 'technique-moment {' frontend/src/App.css | grep -q 'overflow: hidden' && echo 'overflow: hidden ✓' && grep -q 'word-break: break-word' frontend/src/App.css && echo 'word-break ✓' && grep 'technique-moment__source' frontend/src/App.css | grep -q 'max-width: 100%' && echo 'max-width fix ✓'
