Real-photo depth comparison

Detail profile. Same preprocessed input and depth scale for both implementations. Depth is brighter nearby, using CUDA's 2nd–98th percentile range. Error: green is zero; red saturates at 1% of that depth range; magenta marks mask disagreement. These are implementation comparisons, not measured scene-depth ground truth.
