   Mensajes de WhatsApp · Liquid Glass
   Editor de plantillas (Inicio → "Mensajes WhatsApp").

   Todo va scopeado bajo #modal-config-whatsapp para no tocar el resto de
   modales. Se apoya en .modal-overlay/.modal-content de styles.css, que son
   los que ya manejan el abrir/cerrar con la clase .modal-open.

   Sobre los fondos: aquí se usa background-color (y no el atajo `background`)
   en todo lo que tenga !important, para no repetir el bug de las citas, donde
   el atajo borraba los íconos declarados en otra regla.
