The PR description mentions separating Studio from “future root-level content”, but this redirect forces / to always go to /_studio, which would block serving anything else at the root later. Consider removing this redirect (or making it conditional/temporary) so / remains available.

The current rewrite rules don’t provide an SPA fallback for deep Studio routes (e.g. /_studio/settings). /_studio/(.*) -> /_studio/$1 is effectively a no-op and will 404 when the file doesn’t exist. Update rewrites to route all non-asset /_studio/:path* requests to /_studio/index.html (while leaving /_studio/assets/* to serve static files).

{ "source": "/_studio/assets/:path*", "destination": "/_studio/assets/:path*" },
