/* ---------- cs-calendar --------------------------------------------------
   A plan of a few weeks shown as a calendar that follows the reader.
   The board sits in the heading column and stays in view; the weeks are
   written out beside it. assets/js/cs-calendar.js opens the week being read,
   folds the others down to their bars and moves a playhead from Monday to
   Friday as that week's copy scrolls past.

   Base state is the whole calendar, every week open, above or beside the copy,
   so no-JS readers get the plan as a figure. Only .is-live folds anything. */
