   Two panes: a virtualized word list (left) + a word-detail panel

   (css/theme.css) so light/dark track automatically.

   The promo rail is NOT part of this grid — it lives in the page-level
   .layout-with-rail (site.css) wrapping the library AND the editorial block,
   so it can stay stuck past this fixed-height pane.
