  # Auto-publish to PyPI when the version in pyproject.toml has been bumped
  # beyond the latest git tag. Only fires on pushes to main, only after
  # compile+test pass. No-ops on pushes that didn't change the version.
  #
  # Workflow for a release:
  #   1. Open a PR that bumps `[tool.poetry] version` in pyproject.toml AND
  #      adds a matching `## <version> - YYYY-MM-DD` entry to changelog.md.
  #   2. Merge to main.
  #   3. This job auto-publishes to PyPI and creates the v<version> tag.
  #
  # Required repo secret: PYPI_API_TOKEN (a PyPI API token with upload scope
  # for the `smallestai` project).
