+// the React Router request listener as the default export.
+//
+// This module is consumed in two places:
+//   - `app/server/main.ts` — the production bootstrap; wraps the
+//     listener with static-asset serving and binds an http(s) server.
+//   - `runtime/vite-plugin.ts` — the dev-mode Vite middleware; loads
+//     this module through `ssrLoadModule` and dispatches each request.
