   que el arranque (app-bootstrap) agrega sólo en teléfono, en la app
   instalada o cuando se fuerza con ?ba_app=1. El escritorio no cambia.

   Bloques:
     1. Tokens y base del shell
     2. Ocultamiento del chrome del sitio
     3. Barra superior y barra de pestañas
     4. Avisos (sin conexión, actualización, instalación)
     5. Hojas inferiores y ajustes
     6. Aviso flotante (toast)
     7. Ajustes puntuales de páginas existentes
