`git apply patches/vision-camera-isp-off.patch` turns NOISE_REDUCTION_MODE and
EDGE_MODE off for every still JPEG (HybridPhotoOutput.kt) and for the 0.5x path
(UltraWideModule.kt), which is how the two performance APKs were built. Apply
before assembleProRelease / bundleProRelease, revert after; the measured A/B
lives in isp-nr-off.md.
