+`npm run build` loads `.env.production`, which pins `VITE_API_BASE_URL` to
+`https://mcp.nearle.ai.in`. That is right for the deployed site and wrong for
+anything you run locally, because the backend serves `frontend/dist` itself
+whenever that directory exists - so `http://localhost:8000` would hand you a
+page that sends `/api/auth/login` to the remote host and fails with "Could not
+reach the API" even though the local backend is up. For a build you intend to
+run locally, use:
+
+```bash
+npm run build:unified   # same optimised build, blank VITE_API_BASE_URL
+```
+
+That leaves API calls relative, so they go back to whichever server delivered
+the page - port 8000 for the backend's single-port mode, or `npm run preview`,
+which proxies `/api/*` to `127.0.0.1:8000` the same way the dev server does.
