   AYLLU - Design System 2026
   Senior UI/UX guidance, accessibility WCAG 3.0, fluid responsive

   Decisiones de diseño:
   ────────────────────────────────────────────────────────────────────
   1. TOKENS: variables CSS con fallback chain (--primary → :root → color-scheme)
      → Permite tematización por componente sin reflow.
   2. MODO CLARO/OSCURO: prefers-color-scheme + .theme-dark/.theme-light
      con view-transition (Chrome 111+) para morphing visual fluido.
   3. BREATHING SPACE: padding usa clamp() con viewport units,
      escala automáticamente en plegables/triple-pantalla.
   4. CONTAINER QUERIES: layouts adaptan según el contenedor padre,
      no la viewport. Esencial para foldables.
   5. REDUCED MOTION: respeta prefers-reduced-motion estrictamente,
      ofrece transiciones sin transform en su lugar.
   6. INTERACCIÓN MIXTA: hover-only en :hover @media, focus-visible
      para teclado, pointer:coarse aumenta touch targets a 44×44.
   7. COLOR-CONTRAST: ratios WCAG AAA (7:1 texto normal, 4.5:1 grande).
