# T02: Redesigned technique page frontend: meta stats line, video filenames on key moments, monospace signal chain flow blocks with arrow separators

**Redesigned technique page frontend: meta stats line, video filenames on key moments, monospace signal chain flow blocks with arrow separators**

## What Happened

Added video_filename to the TypeScript KeyMomentSummary interface. In TechniquePage.tsx, inserted a meta stats line below the header (source count, moment count, last updated), added video filename display on each key moment row, and replaced ordered-list signal chains with monospace inline flow blocks using cyan arrow separators. Added 5 new CSS classes using only var(--*) tokens. Deployed to ub01 and verified all three visual changes render correctly.

## Verification

npm run build succeeds with zero errors. No hardcoded hex colors outside :root. Browser verification on ub01:8096 confirms meta stats line, video filenames, and monospace signal chain flow blocks all render correctly.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npm run build` | 0 | ✅ pass | 8200ms |
| 2 | `grep -cP hardcoded hex colors outside :root` | 0 | ✅ pass | 100ms |
| 3 | `ssh -A ub01 docker compose build chrysopedia-web` | 0 | ✅ pass | 4700ms |
| 4 | `ssh -A ub01 docker compose up -d chrysopedia-web` | 0 | ✅ pass | 3000ms |
| 5 | `browser: visual verification of all 3 layout changes on ub01:8096` | 0 | ✅ pass | 4000ms |


## Deviations

Docker compose service name is chrysopedia-web not chrysopedia-web-8096. Required ssh -A and stashing ub01 local changes for git pull.

## Known Issues
