ROI is asymmetric: iOS uses Vision's native regionOfInterest and the Android one-shot already crops, but the Android live stream recognizes the full frame and only filters lines whose center falls outside the ROI — correct results, no speed-up.
Add a YUV pre-crop to the Android live path so a smaller ROI actually lowers cost.
