   Componente autocontenido. Usa las variables del sistema de diseño de KEY!
   (--color-*, --font-*, --radius-*, --shadow-*, --transition-*) definidas en
   css/styles.css. Si vas a usar este componente en un sitio SIN esas
   variables, descomenta el bloque :root de "fallback" más abajo.
   Mobile-first: los estilos base son para móvil; el desktop se agrega
   con min-width.
