## Next Steps (Phase 3 - UI with Snapshots)

1. Place your 25-30 design snapshots in `/design-reference/` folder
2. Each snapshot should be named clearly:
   - `college_login.png`
   - `admin_dashboard.png`
   - `student_result.png`
   - etc.

3. The system will then match UI components to your design requirements
