/* ==========================================================================
   Audio guide (.sdg) — a set of recordings as one connected guide, with a
   light player per track (assets/js/audio-guide.js).

   Lifted out of service-details.css so any page can use the guide through
   partials/audio-guide.php without pulling in that page's other 40KB.
   The partial adds this file and its script itself, once per page.
   Orange for play and active states; the secondary controls stay gray.
