/* frogsymbols - tool-specific styling on top of the shared web-tool shell.
   The shell (/shared/tool-shell.css) supplies the :root tokens,
   the topnav header, page-hero, layout, footer, and ad slots in 16px
   Montserrat. frogsymbols' search/grid/export UI is designed for a 13px
   monospace console look, so the tool surfaces scope mono + 13px to
   themselves while the shared header stays sans/16px. */

/* Bundled outline faces. One @font-face per bundled entry in
   js/font-faces.js (cssFamily -> the same TTF). font-display:swap so the
   browse grid never blocks on the multi-MB font: it paints in the native
   font first, then swaps to the face once loaded.

   Face theming mechanism: app.js writes the selected face's cssFamily
   straight onto each grid glyph (.cell-glyph) and the preview meta-glyph
   (#metaGlyph) as an inline font-family ('' for the system face). Inline
   style works for any registry entry without a per-id CSS rule, so adding a
   face stays a one-liner in font-faces.js + one @font-face below. */
