- Page URL paths are now relative to src/pages. The old greedy
`.*/pages/` cut mapped src/pages/admin/pages/index.tsx to /index, so
every page under a nested `pages` directory collided with the home page
and was never bundled. SSR also tells API routes by URL path now.
- CommonJS `require("react…")` in client bundles (for example
use-sync-external-store/shim, pulled in by MUI) threw "Dynamic require
of "react" is not supported" in the browser. Those requires now go
through a small bundled ESM module that imports the external.
