Establish a frame-latency baseline by running 5 × 10s Perfetto captures of CameraActivity on the attached device, force-stopping the app between runs, and printing run-to-run dispersion (mean / stdev / CV%) for every dz.frame_* slice. Use to validate that an instrumentation- or rendering-path change hasn't regressed, or to refresh the baseline numbers on a new device.

Build the camera-fast Android app, install it on a connected device via adb, launch CameraActivity, capture a screenshot, and read the PNG so the result can be analyzed visually. Use when verifying UI changes (edge-to-edge, layout, theming) end-to-end on real hardware.
