   Horse Course — stylesheet
   ============================================================
   Plain CSS, no build step. The old app compiled Tailwind; keeping that would
   have meant running Node on a host that has none, so the same design tokens
   are declared here and used directly.

   Palette sampled from the client's logo:
     shield charcoal #181818 · horse orange #e4903c · jump-bar greys

   The page is RTL Arabic throughout. Use logical properties
   (margin-inline-start, inset-inline-end) rather than left/right, or the
   layout silently mirrors wrong.
