/* ---------------------------------------------------------------
   /listen — synced listen-and-read player

   Follows the design language in style.css: paper ground, hairline
   rules, Zen Old Mincho for display type, filled panel only for a
   distinct surface (here, the player).

   The transcript deliberately uses plain inline spans separated by
   real whitespace text nodes so popup-dictionary extensions can scan
   across word boundaries — do not lay words out with flex/grid, and
   do not disable text selection.
