      Effect.flatMap((req) =>
        pipe(
          Effect.tryPromise(() => renderToReadableStream(<App />)),
          Effect.map((body) => ({ req, body })),
        ),
      ),
      Effect.map(({ req, body }) =>
        HttpServerResponse.raw(body).pipe(
          HttpServerResponse.setHeader('Content-Type', 'text/html'),
