/* =====================================================================
   ADAPTACIÓN A LA PANTALLA DEL EQUIPO

   Las cajas suelen ser monitores de 1024x768 o 1366x768. Ahí lo escaso no
   es el ancho sino el ALTO: la barra superior, el buscador, el carrito y
   la barra de atajos tienen que caber a la vez, porque el cajero no puede
   ponerse a desplazar la página mientras cobra.

   Por eso las reglas van por altura de ventana y no solo por ancho, que
   es como se manifiesta realmente el problema.
