/*
  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, which reads as a broken link
  rather than as a product that is loading.

  In its own file rather than an inline <style>, so the Content-Security-
  Policy in index.html needs no 'unsafe-inline'. No font and no image is
  fetched, so it paints as soon as this small file arrives.

  Colours are TIDE's own (lib/ui/tide_colors.dart): `lightGround` #FFFFFF,
  `accent` #FF6B4A, ink #0A0A0D. TIDE ships a true light theme, so the boot
  screen is light too and hands over to the app without a flash.
