/* ============================================================================
   Alumne Flex — capa de interfaz.

   Esta hoja es COMÚN A TODOS LOS TEMAS y no contiene ni un color literal: todo
   sale de los tokens que aporta el tema activo (webroot/themes/<slug>/).
   Si necesitas un color nuevo, añádelo como token al tema, no aquí.

   Orden de carga en el layout:
     font/fonts.css → vendor/bootstrap → themes/<slug>/theme.css → este fichero

   Secciones:
     1. Puente con Bootstrap
     2. Base
     3. Tipografía y utilidades de texto
     4. Botones
     5. Formularios
     6. Tarjetas, paneles y superficies
     7. Tablas
     8. Badges, tags y estados
     9. Shell: sidebar, topbar, contenido
    10. Patrones: KPI, hero, listas, estado vacío
    11. Pantallas de autenticación
    12. Utilidades y responsive

   1. Puente con Bootstrap
   Se remapean las variables de Bootstrap 5.3 a los tokens. A partir de aquí,
   los componentes de Bootstrap (modal, dropdown, offcanvas, alert, grid) salen
   ya con el lenguaje visual de Alumne Flex sin tocar su marcado.
