/* ════════════════════════════════════════════════════════════════════
   FOCUS MODE — Summarisation stage
   Full-viewport, distraction-free editor for one publication's summary.
   Everything is scoped under .evi-focus and uses the app's design tokens
   (see :root in literature-review.css). Editor internals (lists, tables,
   slash menu, floating format bar) come from tiptap-editor-factory.js via
   the shared .psr-val--editing hook — this file only re-sizes them.

   Stacking (all fixed / body-level):
     layer 9000  <  my dialog (inside layer)  <  slash picker 9999
     <  format bar 10000  <  table menu 10100  <  _bsConfirm 99000
