# Publishes when a GitHub Release is published:
#   Releases → Draft a new release → tag e.g. v0.1.0 → write notes → Publish.
# Tag the release to match pyproject.toml's version (that's the version that
# actually gets published). workflow_dispatch is a manual fallback.
# Requires PyPI Trusted Publishing configured at pypi.org (no API key needed).
