            **For code or behavior changes:** run `pnpm changeset`, select `lg-luma`, and commit the generated `.changeset/*.md` file with this PR.

            Choose the semantic version bump that matches the change:
            - **patch** for backward-compatible bug fixes.
            - **minor** for backward-compatible features.
            - **major** for breaking changes.

            A PR without a release changeset does not request an app version bump. Documentation-only or maintenance changes that do not need a release can omit it.

            This comment is informational. Releases are queued in the Version Packages PR and publish only after that PR is merged and CI passes.
