	# We use a trick here: define the concurrency group as 'workflow run ID' +
	# 'workflow run attempt' because it is a unique combination for any run.
	# So it effectively discards grouping.

	# Important: we cannot use `github.sha` as a unique identifier because
	# pushing a tag may cancel a run that works on a branch push event.
