   oscuro del sistema del visitante (@media prefers-color-scheme: dark), pero
   eso hacía que el widget se viera distinto (oscuro) segun cada celular/
   navegador, sin control de marca. Mismo verde/blanco siempre, igual que el
   resto del sitio. No se borran las variables por si se quiere revertir, solo
   se quita el media query que las activaba. */
