/* ==========================================================================
   nastan.io — one stylesheet, no build step.

   The palette is the app's own (web/app/src/app.css): near-black #070a10,
   panel #0e131c, cyan accent in Race mode, amber accent in Test mode. Dark is
   the default because the product is dark; light is a deliberate second look,
   not an inversion. No web fonts: Nunito is named first so a machine that has
   it (the app's overlay face) matches the app, and everyone else gets their
   system UI font at zero cost.
