An organization wants teams to discover a starter workflow in the GitHub Actions new-workflow interface. Which files belong in the organization .github repository?

1. Only a reusable workflow in .github/workflows/ with no template metadata.
2. Store only action.yml and branding metadata under a repository .github/actions directory.
3. A workflow under workflow-templates/ and its matching .properties.json metadata file.
4. Put a workflow only in an ordinary application repository and expect it to appear as an organization template.
