/* Enjambre — estilos v0 (19 ago 2026).
   Tokens de cristal esmerilado ("liquid glass") adaptados de karen-app/static/styles.css -
   misma técnica (superficies translúcidas + blur + brillo de borde), acento propio (violeta,
   #7C5CFF) para distinguirlo de Karen (naranja) a simple vista. Sin build, sin framework. */
