White-preserving primaries matrix (OkLCh hue rotation / chroma scale of each Rec.2020 primary) plus a luminance-preserving green/magenta shadows tint, applied in scene-linear light before the tone map. CPU (colorops::calibrate) and GPU (finish.wgsl) with an equivalence case; seven control specs (calibration.*), a settings group, crs: import (ShadowTint, Red/Green/BlueHue/Saturation) and a Calibration section at the bottom of the Edit panel.
