+  # Opt-in gate for the ROS 2 ament linters that ros2_build.yml enforces
+  # (flake8 / pep257 / uncrustify / xmllint / lint_cmake on jazzy). Runs ONLY on
+  # `git push`, never on commit or `pre-commit run --all-files`, so it does not
+  # slow the normal flow. Needs Docker; no local ROS install. Enable with
+  # `pre-commit install --hook-type pre-push`; skip once with `git push
+  # --no-verify` or `SKIP=ros2-ament-lint git push`.
