<stats-graph> on its own — no panel, fed by a function
The counters
The loop
Try: push Extra work per frame up until the frame graph crosses
its dashed line — the reading turns warm at the same moment. The Breakdown graph
shows the same milliseconds split between move, bounce, clear and paint, so you can see
which phase took them. Then fold the Budget section: the graphs stop drawing
entirely while they are out of sight, which is the whole point of a monitor.
