   Capas:

     2. Semánticos           → superficies, texto, feedback (temas light/dark)
     3. Fundaciones          → tipo, espacio, radio, sombra, motion
     4. Alias de consumo     → nombres cortos para componentes nuevos
     5. Compatibilidad       → alias legacy usados por main.css de este repo

   Regla: HEX / rem / sombras solo aquí. En CSS de página/componentes: solo var().
