Each script launches and closes Chrome through scripts/qa/browser.mjs,
waits on the application through scripts/qa/ready.mjs instead of the
loading screen and fixed pauses, and reads the contract instead of
Cesium where the check is not about Cesium itself.
At 720px and narrower the panels live in the phone shell's tab sheets, so the
camera, scene and map-source tray harnesses open the matching tab (from the
keyboard where they check focus rings) before measuring, wait for the shell to
follow a viewport change, measure the container that actually scrolls, and run
the pin and compact-wing checks at 800px where the narrow desktop dock still
exists.
