/* NEXO · cliente web (celular y PC): estructura común.
   Un solo DOM para las cinco apariencias: este archivo pone la forma y el reparto de espacio; cada tema
   (ui/temas/<id>.css) define las variables de color y retoca las formas que necesite.
   Variables fijas del contrato: --bg --sup --sup2 --bd --tx --su --ac --ac-tx --ok --av --ml --r --rg --f-t --f-c --f-n --sh.
   Aquí también viven los valores por defecto, para que la página sea usable aunque un tema no cargue. */
