/*
 * Boot splash — painted by index.html before Angular (and the brand config)
 * has loaded, so nothing here can read the --ui-* tokens. It has two looks:
 *
 *   neutral  first visit to a brand in this browser: plain ground + spinner
 *   branded  repeat visit: the inline script in index.html reads the brand's
 *            last-seen logo and colours (saved by ThemeService under
 *            "<brandFlavor> splash") and sets them as --splash-* on the
 *            element before first paint
 *
 * AppComponent fades it out once the theme has been applied, so the page
 * underneath never shows in the default palette. CSS only — no gif, no
 * fonts, no images other than the brand's own logo.
