	// Unify if Class is known.
	// If Class is NOT in #Classes, this might fail or do nothing depending on CUE logic.
	// Actually, `#Classes[Class]` fails if key is missing.
	// This ensures we validate against known classes.
	// If we want to allow unknown classes, we need a check.
	// But spec implies validation should check known classes.
