   EduKinesis — Design System / Base Tokens
   --------------------------------------------------------------------------
   Etapa 1 (claude/design-system): SOLO tokens + reset + tipografía base.
   El maquetado de secciones llega en la Etapa 2 (claude/landing-v1).

   Paleta de marca OBLIGATORIA (logo puzzle 3D). Todos los pares de color
   fueron verificados contra WCAG 2.1 (ver DESIGN.md → "Contraste").
   Estilo visual: Claymorphism-lite (suave, redondeado, sombras dobles
   sutiles) — coherente con el puzzle 3D, pero contenido y profesional.
