   @if ($userPreferences['notifications'])
       <p>Notifications are enabled.</p>
   @else
       <p>Notifications are disabled.</p>
   @endif

For data that depends on the request or user context, use middleware.

   namespace App\Providers;

   use Illuminate\Support\ServiceProvider;

   class CustomDataServiceProvider extends ServiceProvider
   {
       public function boot()
       {
           // Example data
           $globalPreferences = [
               'api_limit' => 100,
               'app_mode' => 'live', // 'maintenance' or 'live'
               'feedback_form_enabled' => true,
           ];

           // Share this data globally
           view()->share('globalPreferences', $globalPreferences);
       }
   }

The data shared via view()->share is now available globally in all Blade templates.
