/* Sticky table header — opt-in via the --sticky modifier on the wrap.

   scroll container on BOTH axes; a sticky thead therefore resolves against this
   wrap, not the page. Giving the wrap a bounded height turns it into a real
   vertical scrollport, so the header pins to its top while the body scrolls.
   Tune per page with --table-sticky-max-h. */
