/* =====================================================================
   DECK EDITOR — three-pane card editor
   Bob and Mariel Ward School of Filipino Languages
   =====================================================================
   Replaces the 11-column table and the separate Lesson Organizer tab.

   Layout: a fixed-height grid of rail | list | inspector. Fixed height is
   what lets the list virtualise — it needs a scroll container with a
   known viewport, which a page that grows to fit 894 rows cannot give it.

   Widths come from container queries on the editor itself, not the
   window: the list narrows when the inspector opens, when the rail opens,
   and when the browser chrome changes, and only one of those is a window
   resize.
