	# WHY-FILE: Minimal checks for specification repositories.
	# REQ: Any check that can be run locally MUST be available locally via pre-commit.
	# REQ: CI MUST NOT introduce arbitrary rules that are not reproducible locally.
	# OBS: CI does not introduce additional style rules beyond repo configuration.
