## 💡 Technical Details

### Live Preview System

**How it works**:
```typescript
// 1. User makes change in editor
handleVariantChange(elementName, variant)

// 2. Editor dispatches custom event
window.dispatchEvent(new CustomEvent('elementor-change', {
  detail: { elementName, variant, visible }
}))

// 3. Hook listens and updates state
useEffect(() => {
  window.addEventListener('elementor-change', handleChange)
}, [])

// 4. Component re-renders with new variant/visibility
<ConditionalElement visible={isVisible('gallery')}>
  <GallerySection variant={getVariant('gallery')} />
</ConditionalElement>
```

### Database Schema

**Updated fields**:
```sql
CREATE TABLE page_element_configs (
  ...
  variant VARCHAR NOT NULL,
  visible BOOLEAN DEFAULT true,    -- NEW
  display_order INTEGER DEFAULT 0  -- NEW
)
```

### Save Without Reload

**New behavior**:
```typescript
// OLD: Page reload after save
window.location.reload()

// NEW: Just save to database
await batchUpdatePageElementConfigs(configs)
toast({ title: 'Saved without reload!' })
```
