│   ├── block.json
│   ├── edit.js
│   └── save.js
├── team/
├── social-icons/

```

### Consistency

All blocks follow these patterns:

1. **block.json**
   - `apiVersion: 3`
   - `namespace: "im-press"`
   - `category: "im-press"`
   - Proper icon names from WordPress icon set
   - Complete attribute definitions with defaults

2. **edit.js**
   - InspectorControls for all settings
   - BlockControls for quick actions
   - RichText or TextControl for content
   - MediaUpload for images
   - ColorPalettePanel for colors
   - Live preview in editor

3. **save.js**
   - Inline styles only (no CSS classes)
   - Responsive design (max-width: 768px)
   - SVG icons embedded
   - Interactive scripts in `<script>` tags with `dangerouslySetInnerHTML`
   - Proper accessibility (alt text, aria-label, title attributes)
   - Touch device handling

### WordPress Compatibility

- **PHP 7.4+** - No deprecated functions
- **React 18+** - Hooks-based components
- **Block Editor 13.0+** - Latest inspector controls

### Performance

- Inline styles (no external CSS needed)

- CSS media queries for responsive behavior
- Touch event delegation for efficiency

### Accessibility

- Semantic HTML (h2-h5, p, a, button)
- `aria-label` on interactive elements
- `title` attributes for tooltips
- Proper contrast ratios (WCAG AA)
- Keyboard navigation support
- Touch device fallbacks
