/* Boot screen shown while the Flutter engine loads. In a file rather than an
   inline <style> so the Content-Security-Policy needs no 'unsafe-inline'. */

/*
  main.dart.js is several megabytes and the engine needs a moment after it
  to paint. Without something here the first thing a visitor sees is an
  empty white page for ten to twenty seconds — and white, on a terminal
  whose ground is near-black, reads as a broken link rather than as a
  console that is loading.

  This file is small and same-origin: no font and no image is fetched, so
  it paints on the first frame and costs nothing against the bundle it is
  covering for.

  Colours are Token Forge's own (lib/ui/theme.dart): `ground` #0A0D11 and
  `accent` #E8B04B, the gold that marks an irreversible action.
