 here; real Pixi checks are part of the integration pass. No battle rule or golden result is intentionally changed.
 
+Real Chrome verification additionally renders one actual Spine death against continual forced updates through
+mixing and the held final frame (40 pixel comparisons over 600 frames), checks revival and the actor clock under the held-update policy,
+and reloads Bender after a shared label was rasterised. The label updates in place and DPR variants stay separate.
+This verifies correctness on that model; it is not a new performance benchmark or a full-roster pixel claim.
