+I.6b moved the complete Phase-6 body into
+`LivePresentationCompositionPhase`. The phase now owns the canonical live
+runtime/world identity, live presentation and effect controllers, WB draw and
+landblock publication owners, selection/radar authorities, optional paperdoll,

+anonymous Phase-6 subscriptions. A deferred landblock-loaded sink preserves
