Jank A/B script for the phone (scripts/jank_ab.sh)
One-shot: install release APK, verify thread priorities (thumb-* nice 2,
slint vsync nice 0), then two 30 s user-scroll windows — real textures vs
grey 1x1 images — with SCRDBG cadence analysis (on-grid %, stalls, p95,
worst). Decisive fork: real-janky+grey-smooth -> texture/GPU path; both
janky -> base render/present path; both smooth -> priority fix worked.
Dry-run tested on the emulator (grey knob detection, priority readback).
