/* ═══════════════════════════════════════════════════════════════════════
   Tema del portal de soporte
   ═══════════════════════════════════════════════════════════════════════

   Sistema visual común para las pantallas públicas y la base de conocimiento.
   La estética sigue la referencia de administración que pidió el cliente
   (navy profundo + azul de acción + ámbar de acento, tarjetas de borde suave
   y tipografía Rubik). El CSS es propio: sólo se replica el lenguaje visual,
   no se reutilizan hojas de estilo de terceros.

   Convive con Metronic: todo va prefijado con `sp-` (support portal) para no
   pisar las clases `m-` del maquetado heredado.
