## Testing Checklist

Test on these viewport sizes:

- [ ] **iPad Pro** (1024x1366) - large tablet

## Browser Compatibility

Tested and working on:
- Safari (iOS 15+)
- Chrome (Android 10+)
- Chrome/Firefox/Safari (desktop)

## Known Limitations

1. **Rich Editor** - Some advanced formatting may be easier on desktop
2. **DataGrid** - Horizontal scroll required for all columns on narrow screens
3. **Media Library** - Smaller thumbnails on mobile (150px vs 200px)
4. **Stepper** - Requires horizontal scroll on very narrow screens (<375px)

## Future Enhancements

Consider implementing:
- **Drawer sidebar** on mobile (slide-in from left)
- **Compact stepper** (dropdown selector on mobile)
- **Swipe gestures** for step navigation
- **Pull-to-refresh** for posts list
- **Touch-optimized rich editor** toolbar

## Deployment

After making these changes:

```bash
# Rebuild admin container
docker-compose up -d --build admin

# Or rebuild all
docker-compose up -d --build
```

Access at:
- Local: http://localhost:3300
- Production: https://your-domain.com

## Viewport Meta Tag

Already present in `index.html`:
```html
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
```

This ensures proper scaling on mobile devices.
