/* exam.4ab.in — Notes Maker (app/notes.html), Brief 5-F1.
   Loads after tokens.css + app.css. Every colour still comes from a token —
   this file only adds the components those two do not already have: the
   picker (topic/chapter tabs, level/lang/mode), the worked-example and
   practice cards, the AI section, the export bar, and the "My notes" list.
   Print handling reuses the existing `.noprint` convention from topic.html's
   header, plus a `@media print` pass here that hides the picker/toolbar/AI
   button/export bar so only the notes content itself prints.

   are numbered and grouped that way, and the one action on the page gets
   a footer of its own instead of being the last item in the pile.
