/* font.css — single home for all typography. Generated by tools/_fontgen.js,
   then hand-tuned. Loaded BEFORE styles.css. All app font-size lives here.

   - --fs-* / --icon-* vars are the knobs; grouped rules below bind selectors.
     Edit a size in ONE place: its :root base below.
   - The -/+ UI buttons step every --fs-* along a shared size ladder (good sizes only,
     skips blurry ones), as an offset from base — handler in js/ui-init-startup.js.
     Export vars (--fs-export-*) are NOT stepped.
   - Icons are inline SVG sized by --icon-*; fixed by default, switch a group to
     var(--fs-*) to make it follow text. */
