   Se carga desde los layouts pagina_principal y pagina_principal_modulo,
   por lo que aplica a todas las páginas públicas: barra institucional,
   cabecera, footer compacto, botón/panel de ayuda flotante y "volver arriba".
   Los estilos de secciones concretas (hero, accesos rápidos, MyLOFT) solo
   tienen efecto en las vistas que usan dichas clases.
   Paleta institucional: azul #003866, celeste #78b8e5, blanco, grises claros.
