	# Standalone secret scan. Previously a thin caller of
	# `hyperpolymath/standards/.github/workflows/secret-scanner-reusable.yml`
	# with `secrets: inherit`; that cross-repo dependency startup-failed (the
	# caller's `concurrency:` block stacked on the reusable's — the BP008 class,
	# see spark-theatre-gate.yml) and required inheriting org secrets. This
	# self-contained version runs a pure-shell high-confidence scan
	# (tools/ci/secret-scan-standalone.sh), needs no secrets, and as a normal
	# workflow can keep its concurrency block.
