	name: publish-python

	# Publishes the `metaobjects` Python package to PyPI via Trusted Publishing (OIDC) —
	# no API token. PyPI mints short-lived credentials after validating GitHub's OIDC
	# token against the trusted publisher configured for the project. See docs/RELEASING.md.
	#
	# One-time setup on PyPI (project `metaobjects` -> Settings -> Publishing ->
	# Add a new GitHub publisher):
	# Owner: metaobjectsdev
	# Repository: metaobjects
	# Workflow: publish-python.yml
	# Environment: (leave empty unless you uncomment `environment:` below)
	# Once that's added you can DELETE any long-lived PyPI API token.
	#
	# Triggers: manual (workflow_dispatch) or a python-v* tag.
