	name: JS port barrier-read lint

	# Enforce the surface-id render invariant: the JavaScript port's worker must
	# never read dimensions/pixels back off a canvas / 2D-context host-ref across
	# the worker<->host barrier. Such reads can return a degraded value and livelock
	# invokeJsoBridge's retry, wedging the worker (observed: the EDT parked on
	# getter.width@HTMLCanvasElement during a form transition). Dimensions/pixels are
	# kept Java-side; this lint fails the build on any regression.
