Bakes a chain of pointwise steps into a 3D LUT over sRGB-encoded [0, 1]³ (the convention
applyLut uses): every grid point goes through the CPU reference chain once. A look written as
readable adjustments then costs a single LUT lookup per pixel. Values outside [0, 1] are clamped
by the LUT, so HDR highlights do not survive a baked grade.
