	# Standalone governance gate. Previously a thin caller of
	# `hyperpolymath/standards/.github/workflows/governance-reusable.yml@main`;
	# that cross-repo dependency (a) coupled this repo's CI to another repo's
	# moving `@main` and (b) startup-failed because a `concurrency:` block in a
	# reusable-workflow caller, when the reusable also declares concurrency on the
	# same key, is rejected at run-creation (the BP008 class — see
	# spark-theatre-gate.yml's note). This self-contained version runs the repo's
	# own conservative, delta-aware checks (tools/ci/governance-standalone.sh) and
	# is a normal workflow, so the concurrency block is safe to keep.
