### Additional Information

Parent Epic: https://github.com/hackforla/lucky-parking/issues/726

Start by reading parent epic #726, then inspect the repository’s YAML template files and issue-template configuration to identify the approved design and affected templates. Compare active and retired templates, labels, title prefixes, and project defaults against that decision; done means the configuration matches it without disrupting active work and the pull request includes a migration summary.
