+# RemoteRig — Pi-side deploy script
+# Deploys a new binary with backup, health-check, and automatic rollback.
+#
+# Usage:
+#   sudo ./deploy.sh [BINARY_PATH] [DEPLOY_PATH] [SERVICE_NAME]
+#
+# Defaults:
+#   BINARY_PATH   = ./remoterig (new binary to deploy)
+#   DEPLOY_PATH   = /opt/remoterig/remoterig
+#   SERVICE_NAME  = remoterig
+#
+# Examples:
+#   # Deploy locally-built binary with defaults
+#   sudo ./deploy.sh ./remoterig
+#
+#   # Custom paths
+#   sudo ./deploy.sh /tmp/remoterig-arm64 /opt/remoterig/remoterig remoterig
