/**
 * Initial-load indicator styles.
 *
 * Loaded from `public/` as an external stylesheet so the deployed
 * Content-Security-Policy (`style-src 'self'`) covers it without hashes.
 * See assert-csp-safe.mjs for why inline <style> is forbidden.
 *
 * Dark-mode awareness: `theme-init.js` adds `.dark` to <html> before
 * this stylesheet paints, so the correct palette is applied on the very
 * first frame.
