/* ==================================================================
   COLD2HORSE — CARRITO

   El cajón que abre el enlace «Carrito» y el botón de añadir de la
   ficha. Va en hoja propia, como menu.css y cookies.css, porque lo
   cargan las quince páginas.

   Los tokens (--ink, --paper, --ice, --hair, --ease) vienen de
   base.css. La escalera de unidades repite el patrón de .qty de
   producto.css, pero con su propio nombre: aquella hoja sólo la
   cargan las cuatro fichas y el cajón sale en todas partes.
