   El color y la tipografía se controlan desde el backend
   (Apariencia → Colores y fuentes) mediante variables CSS.
   Este archivo es el mismo para todos los clientes; solo cambian
   los valores de --srb-* inyectados como inline style.
   Fallbacks abajo cubren el caso de que el backend aún no haya
   generado las variables (p.ej. antes de la primera carga admin).
