   Fondo luminoso (blanco / slate ultra-claro), texto antracita y un color por
   colectivo. Los componentes leen el color activo de las variables --tone-*,
   que fija cualquier clase .tone-<colectivo> en un ancestro.

   Nota: Tailwind Play CDN inyecta su preflight DESPUÉS de esta hoja y resetea
   `[type=button]` a fondo transparente (especificidad 0,1,0). Los fondos de los
   botones de componente usan la clase duplicada (.btn-skew.btn-skew) para
   ganar esa cascada sin recurrir a !important.
