   Felipe Rojas — Mentoría Ejecutiva
   Dirección visual: académica / ejecutiva premium, CÁLIDA.
   Base clara (piedra/marfil) dominante · acentos tinto/borgoña ·
   azul profundo institucional como ancla · bronce en detalles.
   Evitar blanco puro y estética de "coach motivacional".

   GANCHOS DE IMAGEN DE FONDO (para Codex / cuando lleguen los fondos):
   defínelos en :root y caen automáticamente sobre su degradado de
   respaldo. Ejemplo:
     :root {
       --img-boardroom: url("img/sala-consejo.jpg");  (hero-panel)
       --img-contacto:  url("img/aula-direccion.jpg"); (page-hero-dark)
       --img-wall:      url("img/textura-piedra.jpg");  (fondo global)
     }
   Sobre cada imagen va un velo oscuro para mantener legible el texto.
