## Configuration Requirements

### Settings (AgdarCentre/settings.py)
Ensure the following are configured:

```python
# Media files configuration
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

# Authentication
LOGIN_URL = '/accounts/login/'
LOGIN_REDIRECT_URL = '/'

# Password validation
AUTH_PASSWORD_VALIDATORS = [
    # ... password validators
]
```

### URL Configuration (AgdarCentre/urls.py)
Ensure media files are served in development:

```python
from django.conf import settings
from django.conf.urls.static import static

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
```

## API Endpoints (Future Enhancement)

The following API endpoints can be added for mobile/SPA support:
