Research direction
Reproduce the issue in packages/rn-tester by opening APIs → Animated → Transform Styles on iOS with the new architecture and bridgeless mode enabled. Test rotateX, rotateY, and both together, then trace the Animated transform path to identify why the artifacting occurs. Done means those rotation animations render without severe artifacting.
