   LA MARCA SE CAMBIA AQUÍ: --accent (modo claro) y --accent en el
   bloque oscuro. Todo lo demás del acento (hondo, tinte, línea) se
   deriva con color-mix. El color afirma algo:
     --accent  = lo importante (acción principal, dato clave)
     --ok      = bien
     --warn    = atención
   Nada de color decorativo.
