/* ==========================================================================
   Billing scene (template-parts/scene-bill.php, assets/js/scene-bill.js).
   A claims batch where one held line is rechecked, sent and paid. The markup
   renders the finished batch and the script replays it. The card keeps one
   height in every frame: rows have fixed tracks, the held-line panel is
   overlaid, and states change with opacity, colour and transform only.
   Every selector is scoped to .h-scene-bill.
