   Responsive text-button icon rule:
   - Text buttons (.btn) hide their leading icon on
     wide screens (≥768px) so the action label leads.
   - Icon reappears below 768px when label may wrap or
     get truncated, giving users a recognisable glyph.
   - Opt-out: add .icon-keep on the <svg> to always show.
   - Icon-only buttons (.btn-icon-circle, .btn-icon-only,
     .nav-link, .ct-tab/.tab-item, etc.) are unaffected.

/* Caret-drift fix — GLOBAL, every CodeMirror in the app (owner UAT 2026-06-24:

   getBoundingClientRect (visual/zoomed px) but lays text out in unscaled px, so
   under any non-1 zoom the caret drifts left, cumulatively worse along the line.
   `zoom` is multiplicative down the tree, so counter-zooming each editor by
   1/--ui-scale gives it a *net* zoom of 1.0 → measurements correct, no drift.
