+
+Deploy all changes to BOTH servers (primary: 192.168.1.228, secondary: 192.168.1.198).
+
+## Steps
+
+1. Run:
+   ```bash
+   ./scripts/deploy-to-target.sh --both
+   ```
+
+2. This builds on the primary server first, then copies built artifacts to the secondary.
+
+3. Verify both servers respond:
+   ```bash
+   sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.228 'systemctl is-active archipelago'
+   sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.198 'systemctl is-active archipelago'
+   ```
