   BRÚJULA · Núcleo Operativo — Grupo QBK S.A.S.
   public/assets/css/brujula-fase3.css  ·  Diseño (Fase 3)

   Se carga DESPUÉS de brujula.css. Añade:
     1. Modo oscuro por prefers-color-scheme y por [data-theme="dark"]
        — sin !important, solo redefiniendo variables.
     2. Responsive para <768 px: sidebar en drawer, tablas con scroll,
        cards apiladas.
     3. Skeleton loaders reutilizables (`.brj-skel`).
     4. Estados vacíos ilustrados (`.brj-empty`).
     5. Sistema de espaciado en múltiplos de 4 (--gap-{1..8}).
     6. Botón de tema en el topbar (`.brj-tema-btn`).

   Diseño: como brujula.css usa variables CSS, alcanza con reasignarlas
   dentro de un selector de tema para cambiar TODA la interfaz.
