   PANEL ADMIN — Congreso Antifraude Costa Rica 2026 (ACFE CR)

   Capa visual que se carga SIEMPRE de ultimo, despues de style.css
   (INSPINIA). No cambia datos, estructura ni navegacion: solo
   reescribe el aspecto del panel para que combine con el campus y
   con el sitio publico. Se puede revertir borrando este archivo
   y su <link> de las paginas.

   Paleta: la misma del logo del congreso (navy / teal / dorado),
   identica a css/custom.css y assets/css/campus-custom.css.
