/* ---------------------------------------------------------------
   Motor del deck: escenario, sidebar, navegacion y barras.

   Compartido por kunawa, izzi-96 y campus. No contiene nada de
   contenido ni de marca: los colores salen de las variables que cada
   proyecto define en su :root.

   Puntos de extension:
     --sb-sub-max    alto maximo del submenu abierto (def. 420px)
     --c-cta-text    color del texto del boton CTA   (def. --c-white)

   Los selectores #mb-zonas / #mb-zonas-bg son un popover secundario
   opcional: si el proyecto no lo tiene en su HTML, la regla no aplica.

   Este archivo es la fuente de verdad. Cada proyecto recibe una copia
   en assets/deck.css generada por packages/deck/sync.mjs, que esta
   ignorada por git. No edites la copia.
