   Este archivo define los tokens (colores, tipografía, espaciado) y los
   componentes base del subdominio. Se carga en TODAS las páginas a través
   de includes/header.php.

   Principios:
   - Paleta basada en los azules corporativos ya definidos en la memoria
     del proyecto (--cm-primary, --cm-navy, --cm-orange).
   - Mobile-first, rem para rhythm vertical, px para gaps internos.
   - Tarjetas con franja de color en el header (patrón .sw-ch del proyecto).
