/* ═══════════════════════════════════════════════════════════════════════
   INCLUIA — Sistema de diseño global
   Principio: blanco dominante, minimalismo extremo, una acción por pantalla

   Unificado 2026-08-08 con el sistema real del sitio público (ver
   home.php / docs/Incluia-Manual-de-Imagen.html): el admin tenía su propia
   paleta divergente (acento morado, tipografía Inter vía Google Fonts) —
   pasa a los mismos tokens de marca (azul/verde, tipografía de sistema).
   Se mantienen los NOMBRES de variable existentes (--c-purple, etc.) para
   no tener que tocar cada vista que los referencia — solo cambian los
   valores. Nunca cargar fuentes externas: ver regla en el manual de marca.
