/*
 * Splash screen shown while the app loads (#splash in index.html). Plain CSS in
 * its own file: it styles the page before the app's stylesheet arrives and passes
 * a strict Content-Security-Policy. src/lib/splash.ts fades it out once the first
 * page has rendered. Colours mirror the tokens in src/index.css; the theme comes
 * from public/theme-init.js, which runs first.
