/* Material Symbols
   The icon font is self-hosted (public/assets/fonts) so icons never depend on a
   third-party CDN at runtime: if fonts.googleapis.com is blocked, slow or fails,
   the ligature names (e.g. light_mode) previously leaked into the UI as visible
   words. The font-family declaration below is what binds the class to the font,
   so it must stay here even though the page also links the Google stylesheet. */
