   Para cambiar el color principal del sitio (ej: pasar a "azul
   francia"), modificá SOLO las variables acá abajo, en :root.
   Todas las páginas (Inicio, Quiénes somos, Listado, Detalle) y el
   menú superior/lateral toman sus colores de estas variables.

   Ejemplo — azul francia:
     --accent: #4169e1;
     --accent-dark: #2a4bb8;
