**Next Priority:** Phase 4 - Events Module Implementation

## Development Notes
- All frontend pages are standalone HTML files
- Backend APIs return JSON responses only
- Frontend uses AJAX for all data operations
- Clean separation allows independent frontend/backend development
- AdminLTE v4 provides modern, accessible UI components
