+# NGINX CONFIG & SSL DEPLOYMENT SCRIPT (Python Version)
+#
+# This script follows a robust, idempotent deployment strategy.
+# 1. It first ensures all required SSL certificates exist using Certbot.
+# 2. It then deploys the perfected, local Nginx configurations.
+# This prevents Certbot from ever creating a broken Nginx configuration.
+#
+# USAGE:
+# 1. Ensure your local `sites-available` files are correct and complete.
+# 2. Run the script: `python3 deploy_nginx.py`
+# ==============================================================================
