	# For PRs, later CI runs preempt previous ones. e.g. a force push on a PR
	# cancels running CI jobs and starts all new ones.
	#
	# For non-PR pushes, concurrency.group needs to be unique for every distinct
	# CI run we want to have happen. Use run_id, which in practice means all
	# non-PR CI runs will be allowed to run without preempting each other.
