/* styles.css — visor RAR para Drive.
   Dirección: herramienta utilitaria que debe sentirse INSTANTÁNEA y de
   confianza (el pitch es "tu archivo nunca sale de tu navegador").
   - Fuentes del sistema: cero latencia de webfonts en una app que se abre
     desde un menú contextual.
   - Firma visual: las barras de tamaño relativo integradas en el árbol
     (se ve de un vistazo qué pesa dentro del archivo) en verde azulado.
   - Todo lo demás, quieto y disciplinado. */
