/* =============================================================================
   Design tokens — adaptados del kit de miuif

   Oscuro es el default de este sitio (:root). Claro vive en
   html[data-theme="light"]. La marca se queda en #003799 en los dos temas:
   el kit aclara el azul en dark (#3b82f6) y aquí los botones dejarían de leerse.

   No incluye la capa de compatibilidad del kit (--ink, --muted, --ring, …):
   en este CSS esos nombres ya significan otra cosa. Tampoco carga Geist;
   la familia apunta a Inter, que es la fuente del sitio.
