+
+Deploy all changes to the live server (192.168.1.228).
+
+## Steps
+
+1. Run the deploy script from the project root:
+   ```bash
+   ./scripts/deploy-to-target.sh --live
+   ```
+
+2. This syncs frontend and backend code, builds the Rust backend **on the server** (never locally on macOS), deploys frontend to `/opt/archipelago/web-ui/`, deploys backend binary to `/usr/local/bin/archipelago`, and restarts systemd + nginx.
+
+3. After deploy completes, verify the server is healthy:
+   ```bash
+   sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.228 'systemctl is-active archipelago nginx && sudo journalctl -u archipelago -n 10 --no-pager'
+   ```
+
+4. Report whether the deploy succeeded and if any errors appeared in the logs.
