/* ============================================================================
   CHAT EN CELULAR (pantallas de 767px o menos)
   - Pantalla completa, cabecera compacta, etiquetas en una fila.
   - Abajo: "+", caja de texto y micrófono/enviar, como WhatsApp.
   - El "+" abre un panel de acciones en el lugar del teclado.
   - El chat mide lo que queda libre arriba del teclado (ver js/crm/chat-movil.js).
   En computadora y tablet no cambia nada.
