   CECATI 106 — CAPA VISUAL PREMIUM (inspiración institucional UGC)
   ---------------------------------------------------------
   Dirección de arte: institucional / universitario, rojo-guinda
   protagonista, blanco cálido, gris carbón, acento dorado sutil.
   Editorial, con aire, jerarquía y microinteracciones humanas.

   REGLAS DE SEGURIDAD (para no romper nada):
   - SOLO visual. No toca textos, IDs, anclas, enlaces ni JS.
   - Se carga AL FINAL de todas las hojas → refina por cascada.
   - Los cambios de COLOR/FONDO de superficies claras van acotados
     con  body:not(.a11y-dark):not(.a11y-contrast)  para respetar
     el modo oscuro y el alto contraste.
   - Sin !important en propiedades que gobierna el alto contraste.
   - 100% REVERSIBLE: quitar este archivo y su <link> deja el sitio
     exactamente como estaba.
