/* Educator Hub.
   Sits on top of ../dashboard-new.css (which imports landing-new.css), so the
   header, rail, tabs, cards and footer are the learner dashboard's own. This
   file adds only what the hub needs, namespaced .hub-* / .room-* / .deck-*.

   Theming: the shared stylesheets hard-code their dark colours per component.
   Everything new here reads the --hub-* variables below instead, so a component
   is written once and both themes follow. */
