### Step 2: Register Blocks
In your main plugin file (im-press.php):

```php
function im_press_register_blocks() {
    $blocks = [
        'product-grid',
        'product-categories',
        'cart-button',
        'mini-cart',
        'account-page',
        'checkout-fields',
    ];
    
    foreach ( $blocks as $block ) {
        register_block_type( __DIR__ . '/src/blocks/' . $block );
    }
}
add_action( 'init', 'im_press_register_blocks' );
```

### Step 3: Build (Optional)
If using build tools:
```bash
npm run build
```

### Step 4: Test
Open Gutenberg editor and search for blocks under "IM-Press" category.

## Requirements

- WordPress 6.0+
- Gutenberg 13.0+
- WooCommerce 6.0+
- PHP 7.4+

## Architecture

All blocks use **server-side rendering**:
- `block.json` - Register block with Gutenberg
- `edit.js` - Editor interface with React
- `save.js` - Returns `null` (no static HTML)
- `render.php` - Server-side PHP handles live data

This approach is required for WooCommerce blocks because:
- Product data is dynamic and user-specific
- Cart contents change based on user actions
- Account page shows authenticated user data
- Can't be statically cached

## Security

All code includes:
- Input sanitization (`sanitize_text_field`, `sanitize_hex_color`)
- Output escaping (`esc_html`, `esc_url`, `wp_kses_post`)
- Nonce verification ready
- No hardcoded sensitive data
- Full WordPress security standards

## Styling

All blocks use:
- Inline CSS in render.php (no external sheets)
- CSS custom properties for dynamic values
- Responsive design with media queries
- Production-optimized selectors
- Accessibility-friendly defaults

## Browser Support

- Modern browsers (Chrome, Firefox, Safari, Edge)
- ES6+ JavaScript
- CSS Grid & Flexbox
- Mobile responsive

## Customization

Each block is highly customizable through:
- Inspector panel color pickers
- Range controls for sizing
- Toggle switches for features
- Dropdown menus for layouts/styles
- Text inputs for content

## Performance

- Optimized database queries
- Lazy loading support
- Pagination for large product lists
- Efficient CSS selectors
- Minimal JavaScript overhead
- Smart caching compatibility

## Accessibility

- Semantic HTML structure
- ARIA labels where needed
- Keyboard navigation support
- Color contrast compliant
- Screen reader friendly
- Focus management

## Support & Troubleshooting

### Blocks don't appear in editor
- Verify WordPress 6.0+
- Check WooCommerce is active
- Check block registration in functions.php
- Enable WordPress debug mode

### Products not showing
- Verify WooCommerce is installed
- Check products exist in admin
- Test with sample products
- Check category/tag slugs

### Styling issues
- Clear browser cache
- Check CSS cascade in theme
- Test with default WordPress theme
- Review inline CSS in render.php

## Code Quality

- WordPress Plugin Handbook standards
