/* ===================================================================
   Skin "Santa Barbara" para AdminLTE 4 / Bootstrap 5.3
   -------------------------------------------------------------------
   PRINCIPIO: lo UNICO que cambia respecto de AdminLTE 4 es la PALETA.
   No se toca layout, estructura, tipografia, espaciado ni comportamiento.
   Todo se resuelve remapeando tokens (CSS custom properties) de
   Bootstrap y AdminLTE. Para cambiar la identidad, editar SOLO este archivo.
