## Testing Checklist

- [ ] Run migrations to create contact tables
- [ ] Access `/admin/kontakty` - verify page loads
- [ ] Create contact categories
- [ ] Add contacts with photos
- [ ] Verify contacts appear on homepage
- [ ] Configure map location in setup or settings
- [ ] Verify map displays correctly
- [ ] Test different map styles
- [ ] Test on mobile devices
- [ ] Verify email/phone links work
- [ ] Test category assignment and filtering

## Next Steps (Optional Enhancements)

From the original `CONTACT_MANAGEMENT.md`:
- [ ] Contact form directly on contact page
- [ ] vCard download for contacts
- [ ] Office hours/availability scheduling
- [ ] Multiple locations/maps support
- [ ] Department-specific contact forms
- [ ] Social media links per contact
- [ ] Search/filter functionality
- [ ] Map clustering for multiple locations

## Security Notes

- Admin endpoints protected by JWT + admin role middleware
- Public endpoints only expose active contacts
- Image uploads validated for file type
- SQL injection protected via ORM (GORM)
- XSS protection via React's automatic escaping

## Dependencies

**Frontend**:
- Leaflet.js 1.9.4 (loaded dynamically, no npm install needed)
- @chakra-ui/react (already in project)
- react-icons/fa (already in project)

**Backend**:
- No new dependencies (uses existing GORM, Gin)

## Support

Map uses OpenStreetMap tiles (free, no API key required). For production:
- Consider using a CDN for Leaflet assets
- Monitor tile server usage (OSM has usage policies)
- Can switch to alternative tile providers if needed
- Custom tile servers can be configured via `map_style` setting
