## Your Task US-021

1. Read the full app PRD at `prd-main.md` (in the same directory as this file)
2. Read the PRD at `prd.json` (in the same directory as this file)
3. Read the progress log at `progress.txt` (check Codebase Patterns section first)
4. **DO YOUR JOB**
5. Update the PRD to set `passes: true` for the completed story

APPEND to progress.txt (never replace, always append):
```
## [Date/Time] - [Story ID]
- What was implemented
- Files changed
- **Learnings for future iterations:**
  - Patterns discovered (e.g., "this codebase uses X for Y")
  - Gotchas encountered (e.g., "don't forget to update Z when changing W")
  - Useful context (e.g., "the evaluation panel is in component X")
