+#
+#Bash script for safe COIN sandbox deployment that prepares new release directories, extracts the release from a Docker image, runs interactive pre-checks (Docker, SSH, DB migrations),
+#supports dry-run and node-specific deploys, and deploys to node-3 and node-4 with logging and safety guards
+# Features:
+#   - Full/partial release deploy to node-3 / node-4
+#   - Manual EXPECTED_MIGRATION_ID check in DB
+#   - Colorful output
+#   - Logging to file
+#   - Interactive SELF-TEST
+#   - Manual stop for editing project.env
+#   - CLI flags:
+#       --dry-run
+#       --self-test-only
+#       --node3-only
+#       --node4-only
+#       --skip-db-check
+#       --skip-self-test
+#       --auto-yes
+#       --deploy-only node3|node4|node3,node4
+#       --help
+#
+#
+#For testing use ./deploy.sh --dry-run --self-test-only
