+#
+# Deploy static files using release directories and an atomic symlink switch.
+#
+# This pattern reduces partial deployments because files are copied to a new
+# release directory first. The live path changes only when the copy succeeds.
+#
+# Usage:
+#   bash deploy_static_site.sh --source ./dist --releases /var/www/releases --current /var/www/current
+#   bash deploy_static_site.sh --source ./dist --releases /var/www/releases --current /var/www/current --keep 10
+#
+# Options:
+#   --source DIR     Directory containing built static files.
+#   --releases DIR   Directory that stores timestamped releases.
+#   --current PATH   Symlink path used by the web server.
+#   --keep N         Number of releases to keep. Default: 5.
+#   --help           Show this help message.
