v1.2.1

Fixed

• Author/maintainer metadata corrected across pyproject.toml, mkdocs.yml,
  and GOVERNANCE.md: earlier boilerplate misattributed the project to an
  unrelated person and referenced a nonexistent contact domain. The project
  is by Zuga Technologies; security contact is buga@zugabot.ai and
  justin@zugabot.ai as in SECURITY.md. The v1.2.0 GitHub Release artifacts
  carry the old metadata; v1.2.1 supersedes them and is the version intended
  for PyPI. No code or signature changes.
