   ----------------------------------------------------------------------------
   Fuente de verdad de la interfaz: colores, tipografía, y componentes
   reutilizables (botones, tarjetas, tablas, formularios, badges, alerts...).

   Reglas:
   - Colores: marca naranja (--brand), neutros slate, semánticos
     emerald (éxito) / red (peligro) / amber (aviso) / blue (info).
   - Radios: tarjetas 12px, controles 8px, pills 999px.
   - Los utilitarios de Tailwind se siguen usando para layout (flex, grid,
     spacing). Estos componentes cubren la apariencia (color, borde, sombra).
