/* =========================================================
   Parlario — user guide (/guides/ and /es/guides/)
   Index: intro, progress card ("X of N lessons viewed" +
   continue button) and one card per module. Lessons: breadcrumb,
   meta line, "What you'll learn", steps with real screen captures,
   callouts, recap, "Mark as viewed", previous/next, support line.
   A sticky side navigation (search, numbered lessons, viewed ticks)
   sits on the left from 1024 px; below that it folds into a
   "Lessons" button. Behaviour: assets/js/guides.js.
