   ──────────────────────────────────────────────────────────────────────────
   Va al final a propósito, como la capa Atlas: pisa lo de arriba sin borrar
   una línea, así volver atrás es borrar este bloque.

   Cuatro problemas concretos del teléfono, no "que se vea responsive":
   1. `height: 100vh` miente en móvil (la barra del navegador se suma y se
      resta): el compositor quedaba debajo del borde. Se usa 100dvh.
   2. El cajón de conversaciones se abría sin fondo: se veía el chat detrás y
      un toque al costado no lo cerraba.
   3. Los botones eran de 28px: abajo del mínimo que un dedo acierta (44px).
   4. Un textarea con letra menor a 16px hace que iPhone haga zoom solo al
      escribir, y después la pantalla queda corrida.

   Con color-mix el halo sigue a --bolt, asi que la piel del cliente se lleva
   tambien el resplandor. Para Hermes el resultado es identico al rgba de arriba:
   color-mix(in srgb, #FFE115 22%, transparent) == rgba(255,225,21,.22).
