/* OJO: styles_preview.css estiliza el menú del header con un selector de
   elemento SIN acotar (`nav { ... }`, líneas ~1216 y ~1313). Esa regla alcanza a
   cualquier <nav> del documento, así que el breadcrumb heredaba la píldora de
   cristal del menú y, por debajo de 968px, el `position:absolute` +
   `transform: translateY(-150%)` del panel móvil — se salía de la pantalla.
   Como no tocamos el CSS de la home, el breadcrumb se defiende aquí: la clase
   (0,1,0) gana al selector de elemento (0,0,1) también dentro de sus media
