/* First-paint loading state. External (not inline) so it satisfies the app CSP style-src 'self' (no
   'unsafe-inline'). Keyed on #root:empty: shows only while the SPA bundle is still downloading/parsing
   (an empty #root) and disappears the instant React renders its first children. #root stays byte-identical
   to what the prerender scripts replace, and prerendered pages ship SSR content in #root so :empty never
   matches there (no overlay on marketing pages). */
