/*
 *  Initial-load splash for the VTClient SPA. Shown by index.html before

 *  are destroyed by Application.launch() once the viewport is up.
 *
 *  Visual: Tangix-blue gradient backdrop + centered VirtualTester
 *  wordmark + minimalist spinning ring. Matches the auth pages
 *  (login.php, forgot, reset) and the MyAccount hero.
