/* ---------------------------------------------------------------------------
   Trusty Track — trusty-track.com landing page.

   The palette is the app's own: --scouting-blue and --cub-scouting-gold are
   the same two custom properties frontend/src/index.css defines, holding
   Field Uniform's own values — the default of the seven themes the app can
   now be set to (#498). This page always shows Field Uniform's colours,
   whichever theme an install is actually running; a landing page has no
   installation to defer to. The cream and wood tones come from the logo's
   pinewood car; they exist to stop a page that is mostly blue and gold from
   reading like a bank.

   No build step and no framework. One stylesheet, one font, everything else
   is the browser's.
