 - OpenNext Cloudflare does **not** support `export const runtime = "edge"`; those exports were removed.
 - Build output is generated under **`.open-next/`** (gitignored).
+- **`open-next.config.ts`** imports `@opennextjs/cloudflare` — that package **must** be installed locally (`npm install`). Using only `npx @opennextjs/cloudflare` without installing deps will fail with “Could not resolve `@opennextjs/cloudflare`”.

+### Troubleshooting
+
+**`ENOENT` / missing `app-build-manifest.json` or `_buildManifest.js.tmp` in dev**
+
+Stop the dev server, delete the cache (`rm -rf .next`), and run `npm run dev` again. Prefer the default dev script (webpack); use `dev:turbo` only if you need Turbopack.

+**`ETIMEDOUT` downloading `workerd` or other npm packages**

+Retry when the network is stable, or use a VPN / different DNS. You can also raise timeouts:

+```bash
+npm config set fetch-timeout 600000
+npm config set fetch-retries 5

+Then run `npm install` again before `npm run deploy`.
