## JavaScript Data Contracts

Each admin page receives properly formatted data:

### Global Config (All Pages)
```javascript
window.mpzConfig = {
  restUrl: string,
  restNonce: string,
  ajaxUrl: string,
  pluginUrl: string,
  version: string,
  darkMode: boolean,
  i18n: {
    save: string,
    cancel: string,
    delete: string,
    // ... 20+ more strings
  }
}
```

### Page-Specific Globals
- `window.mpzDashboard` - Stats and recent activity
- `window.mpzLanguages` - Language list and available options
- `window.mpzTranslations` - Translation data
- `window.mpzSettings` - Plugin configuration
- `window.mpzLicensing` - License status

---

## Admin Menu Structure

```
WordPress Admin Menu
├── Dashboard
├── Posts
├── Media
├── Pages
├── Comments
├── Appearance
├── Plugins
├── Users
├── Tools
├── Settings
└── 🆕 Multilingual ← NEW (dashicons-translation)
    ├── Dashboard
    ├── Languages
    ├── Translations
    ├── Settings
    └── Licensing
```

---

## Asset Loading Flow

```
1. User navigates to plugin page
   ↓
2. WordPress fires admin_enqueue_scripts
   ↓
3. AssetLoader::enqueue_admin_assets()
   ↓
4. Check if plugin page (is_plugin_page)
   ↓
5. Load common bundle (runtime.js)
   ↓
6. Load admin styles (admin.css)
   ↓
7. Add global config (mpzConfig)
   ↓
8. MenuController::enqueue_page_assets()
   ↓
9. Load page-specific bundle (main.js)
   ↓
10. Add page data (mpzDashboard, etc.)
   ↓
11. JavaScript renders UI
```

---

## Testing Instructions

### 1. Activate Plugin
```bash
wp plugin activate multilingual-press-zone
```

### 2. Check Admin Menu
- Navigate to WordPress admin
- Look for "Multilingual" menu item
- Verify translation icon (dashicons-translation)

### 3. Test Each Page
- Dashboard: `/wp-admin/admin.php?page=multilingual-press-zone`
- Languages: `/wp-admin/admin.php?page=mpz-languages`
- Translations: `/wp-admin/admin.php?page=mpz-translations`
- Settings: `/wp-admin/admin.php?page=mpz-settings`
- Licensing: `/wp-admin/admin.php?page=mpz-licensing`

### 4. Verify JavaScript
Open browser console:
```javascript
// Should be defined
console.log(window.mpzConfig);

// Page-specific (on dashboard)
console.log(window.mpzDashboard);
```

### 5. Check Assets
View page source, verify:
- `runtime.js` is loaded
- `main.js` is loaded
- `admin.css` is loaded
- Script tags contain localized data

## Integration Points for JavaScript

### REST API Calls
```javascript
const { restUrl, restNonce } = window.mpzConfig;

fetch(`${restUrl}languages`, {
  method: 'GET',
  headers: {
    'X-WP-Nonce': restNonce
  }
})
  .then(res => res.json())
  .then(data => console.log(data));
```

### AJAX Calls
```javascript
const { ajaxUrl } = window.mpzConfig;

const formData = new FormData();
formData.append('action', 'mpz_save_settings');
formData.append('nonce', window.mpzConfig.restNonce);

fetch(ajaxUrl, {
  method: 'POST',
  body: formData
})
  .then(res => res.json())
  .then(data => console.log(data));
```

### Internationalization
```javascript
const { i18n } = window.mpzConfig;

const button = document.createElement('button');
button.textContent = i18n.save; // Translated "Save" text
```
