   --------------------------------------------------------------------------
   Se apoya en Bootstrap 5.3 sobrescribiendo sus variables CSS (--bs-*), de modo
   que las ~123 plantillas existentes heredan el nuevo aspecto sin tocar su
   marcado. Estructura:
     1. Tokens (color, tipografía, espaciado, elevación)
     2. Tema oscuro
     3. Base y tipografía
     4. Estructura: barra lateral, barra superior, contenido
     5. Componentes: tarjetas, tablas, formularios, botones, badges, estados
     6. Utilidades, impresión y responsive
