	name: Documentation Links

	# Validates that links in the README, readme.txt, and docs resolve — including the
	# WordPress Playground demo links (playground.wordpress.net/?blueprint-url=…) and the
	# raw blueprint URLs they point at. Catches a broken "Try it live" demo in CI instead
	# of by hand.
