-4. In `google_only` mode the proxy only relays `*.google.com`, `*.youtube.com`, and the other Google-edge hosts via the same SNI-rewrite tunnel the full client uses. Other traffic goes direct — no Apps Script relay exists yet.

 5. Do Step 1 in your browser (the connection to `script.google.com` will be SNI-fronted). Deploy Code.gs, copy the Deployment ID.
 6. In the desktop UI or the Android app (or by editing `config.json`) switch the mode back to `apps_script`, paste the Deployment ID and your auth key, and restart.
