        $hero_gradient_start,
        $hero_gradient_end

## How It Works

### Frontend → Backend

2. Clicks "Save Settings"
3. POST to `/notifications/email-settings`
4. Backend sanitizes and stores in wp_options

### Backend → Email
1. Email triggered (order placed, etc.)
2. EmailRenderer loads settings
3. Applies colors, logo, footer
4. Renders with custom branding
5. Sends to customer

### Preview
1. EditTemplate loads settings
2. Applies to preview iframe
3. User sees real-time preview
4. Colors, logo, footer all visible

- `App.tsx` - Added route

### Backend

## Next Steps (Optional Enhancements)

### Button Color Application
Currently ready but needs template update:
```php
$primary_color = $email_settings['primary_color'] ?? '#7f54b3';
$button_text_color = $email_settings['button_text_color'] ?? '#ffffff';

// Apply to .button class in template
```

### Social Icon Assets
Need to create/host social icon images:
- facebook.png
- twitter.png
- instagram.png
- linkedin.png
- youtube.png
- website.png

Or use Font Awesome / inline SVG.

### Preview Integration
Update EditTemplate preview to fetch and apply email settings:
```typescript
const { data: emailSettings } = useQuery({
  queryKey: ['email-settings'],
  queryFn: () => api.get('/notifications/email-settings'),
});

// Apply to preview styles
```
