+name: Stage Versioned Javadocs (Manual Trigger)
+
+# This workflow is triggered manually via Workflow Dispatch on GitHub.
+# It automatically extracts the project version from the root pom.xml 
+# of the branch or tag that you trigger this workflow from.
+# It compiles and packages the javadocs into a structured ZIP.
+#
+# To deploy:
+# 1. Kick off the workflow on your chosen branch or tag.
+# 2. Download the resulting versioned-javadocs-*.zip from the run summary.
+# 3. You have 30 days to download before they are deleted from the server.
+# 4. Extract it directly into your local gh-pages repository clone and push.
