/*
  BOOT SPLASH (residence only)

  Markup lives in index.html; this file styles it. It paints before the JS bundle and the theme CSS
  load, so colors are literal values here rather than theme tokens. src/app/app-splash.ts fades it
  out once the session restore resolves. Served from public/ (not bundled) and precached by the
  service worker as part of the static shell.
