   Monova · botón flotante y pantalla de llamada
   ---------------------------------------------------------------------------
   La pantalla imita una llamada de contacto real: avatar circular con el logo,
   nombre, estado, y fila de controles. Se lee al instante porque todo el mundo
   ha visto esa pantalla antes.

   Verde de llamada propio (#1FD65F), NO el #25D366 de marca de WhatsApp.
   Elevación por luz, no por sombra: sobre #050B14 una sombra negra no se ve.
   Sólo se animan transform y opacity.
