   GANO DESIGN SYSTEM v1.0

   Integración de:
   - Shadcn/ui patterns (componentes)
   - Lucide Icons (1,600+)
   - Phosphor Icons duotone (accents)
   - Motion animations (150-300ms)
   - Tokens Studio + Style Dictionary (design tokens)
   - CSS Grid nativo (responsive sin breakpoints)
   - UI/UX Pro Max rules (accesibilidad + performance)

   Orden de cascada:
   1. CSS Variables (tokens)
   2. Utility classes (spacing, text, etc)
   3. Component styles (button, card, form)
   4. Layout system (grid, flex patterns)
   5. Motion & animation
   6. Dark mode overrides
