/* Bug corregido: .mob-app tiene overflow:hidden y .mob-lobby usaba
   height:100% SIN overflow-y — cuando el contenido (chip de cuenta +
   nombre de grupo + tarjeta con bloques) supera la altura visible real
   (pantallas con más bloques planificados, o el navegador móvil real con
   menos alto útil que el mockup de 844px), el resto del contenido —
   incluidos los botones "Empezar clase"/"Ver detalle completo" — queda
   recortado y es IMPOSIBLE de alcanzar: no hay scroll posible porque el
   padre corta el overflow. Con overflow-y:auto aquí, el lobby scrollea
   internamente y los botones siguen siendo alcanzables aunque el
   contenido no quepa entero. */
