   Only the components that do not already exist in styles.css are defined
   here. Everything else (.page-hero, .split, .grid-3, .grid-4, .list-check,
   .card, .glass-light, .media-ratio-4x3, .credit, .btn) is inherited from the
   main stylesheet so these pages stay visually identical to the rest of the
   BSKL site.
