Stage	Description
LorenzoStage	Plain integer delta predictor / prefix-sum (lossless)
TiledLorenzoStage	Dimension-aware (tiled separable) Lorenzo predictor (lossless, 2D/3D, cuSZp3 delta)
DifferenceStage	First-order difference / cumulative-sum coding

‍Note: GInterpStage lives in Fused stages because the spline predictor and quantizer are intrinsically fused — see the GInterp doc for why a standalone predictor is not feasible.
