/*
  Learn pages, the parts every page shares: headings, a world's hero (path, group, test, My learning) and the gender

  Looks/LearnStyles.cs for which page takes which): today.css ("Where do I start?" and Today), course.css (a path's
  map, a group, a course, the course list, the path test), lock.css (the lock card and the locked page) and me.css
  (certificates, the certificate, My learning). LD2-0 split them out of this file so each can change on its own.
