   MEDINT · Design System
   ---------------------------------------------------------------------
   Capa ADITIVA sobre style.css. No reemplaza nada: extiende los design
   tokens (incluye modo oscuro) y agrega componentes reutilizables.

   Como style.css ya usa var(--surface), var(--text), etc., al redefinir
   esos tokens bajo [data-theme="dark"] TODA la UI existente hereda el
   modo oscuro automáticamente.

   Índice:
     1. Design tokens (light)
     2. Design tokens (dark)
     3. Base / accesibilidad
     4. Botones (variantes, tamaños, loading, icon)
     5. Badges / chips / pills
     6. Alertas / banners
     7. Cards / stat cards
     8. Empty states
     9. Skeletons / spinners (estados de carga)
    10. Avatares
    11. Modal / dialog
    12. Form fields
    13. Switch / segmented control (incl. theme toggle)
    14. Tooltip / progress / pagination
    15. Utilidades
