A simulation store owns one run and one playhead, so the chart and the canvas read off the same instant. While the panel is open, Stocks show a live value and a fill gauge, Flows and Converters their current value; a play/pause + scrubber drives the playhead (a wall-clock-paced clock in usePlayback), and a marker tracks it on the chart.
