/* Nav override for content pages
   On the homepage, the nav sits transparent over the hero video and gets a
   solid background only when scrolled (via JS adding .scrolled class).
   On article/hub pages there's no hero, so the nav needs to be solid
   from the start — otherwise content shows through and collides with the
   breadcrumb and title. Target only pages that add body.content-page. */
