+## Frontend/backend split (spike output)
+- Backend CI (`maven.yml`) now ignores frontend-only changes.
+- Frontend CI (`node.js.yml`) now runs only for frontend/workflow changes.
+- Backend Maven builds are backend-only by default; frontend bundling is opt-in via `-DbundleFrontend=true`.
+- Recommended deployment coordination: publish backend and frontend with the same semantic version and promote both only after compatibility checks.
 ##### See the output below to verify the frontend test suite results.
