+This behavior is due to minor precision noise introduced by the GPU’s accumulation order.
 Because modern GPUs execute operations out of order for better performance, small variations in output can occur, even with the same seed.
 Enforcing strict accumulation order would reduce this variability but significantly hurt performance, so we do not plan to change this behavior.
