# Implementation: Dashboard Task Review and Approval

## Summary

Added a complete review/approval workflow to the dashboard. Tasks can be reviewed, approved, or flagged for changes directly from the UI.

## Changes Made

### Backend (`app.py`)
- `_get_review_status()` — reads REVIEW.md from task folder, parses status/timestamp/comment
- `_write_review()` — writes REVIEW.md with approval status and optional comment
- `_handle_review()` — POST endpoint for review submission
- `_serve_review_summary()` — aggregate review metrics across all tasks
- Integrated review data into task API responses
- Added unquote() for URL-encoded task names

### Frontend (`dashboard.js`)
- Review status badge on each task card (🟡 pending, ✅ approved, ❌ changes requested)
- Review section in detail panel: status display, comment textarea, Approve/Request Changes buttons
- `submitReview()` — posts review to API, closes modal on success
- Review filter dropdown — filter board by review status
- Pending review count in header stats
- `getTaskDisplayGroup()` — approved planning tasks move to Design column, rejected to Blocked

### Styles (`styles.css`)
- `.review-badge` — status indicator styling (approved/requested/pending colors)
- `.review-textarea` — comment input styling
- `.review-actions` — button layout
- `.review-comment` — previous comment display
- `.review-btn` — approve/changes button styles

### HTML (`index.html`)
- Review filter dropdown in filter bar
- Pending review count display in header
