  Convenciones CSS (Web Interface Guidelines / buenas prácticas):

  - Foco: usar :focus-visible y reemplazo visible (outline/ring), no outline: none sin sustituto.
  - Animaciones: respetar prefers-reduced-motion (variante reducida o desactivar).
  - Colores y tamaños reutilizables en :root (variables).
