/* =========================================================================
   Paleta corporativa
   -------------------------------------------------------------------------
   El amarillo de marca (#E5D504) tiene 1.52:1 contra blanco, así que NO es
   un color de texto en modo claro. Por eso la marca se reparte en tres
   papeles y no en un único token de acento:

     --brand       relleno de superficies >=24px, SIEMPRE con --on-brand encima
     --brand-deep  bordes, foco y elementos pequeños (3.98:1 -> UI, no texto)
     --brand-ink   texto, enlaces y estados activos (5.23:1 sobre --bg)

   Regla: un elemento amarillo pequeño sobre fondo claro desaparece. Puntos,
   iconos finos y texto van en --brand-ink o --brand-deep, nunca en --brand.

   En oscuro esto se invierte: #E5D504 rinde 12.31:1 sobre el fondo, así que
   --brand y --brand-ink pasan a valer lo mismo.

   El amarillo es exclusivo de identidad y no participa en la rampa de
   estados: "pendiente" usa pizarra y "aviso" usa naranja, para que el color
   corporativo nunca se lea como un estado del sistema.
