/*
  Sidebar de pedido (carrito) + botón flotante (FAB) en mobile.

  Desktop (>=960px): .page-layout es un flex row — el contenido principal
  (.page-layout__content, que envuelve <main>) y el sidebar conviven lado
  a lado como columnas del mismo layout. El sidebar es sticky dentro de su
  propia columna: nunca se sobrepone al contenido, porque nunca comparte
  espacio con él — cada uno tiene su propio ancho reservado.

  Mobile (<960px): no hay espacio para dos columnas, así que el sidebar es
  un panel fijo oculto fuera de pantalla (translateY) hasta que el botón
  flotante (.order-fab) lo abre — ahí sí se superpone al contenido, como
  cualquier drawer/hoja modal, con un backdrop para cerrarlo tocando fuera.
