Interaction: Hover over or tap a chart to inspect data at different speeds — all panels follow along. Click to lock a speed. The vertical line shows the selected point or the equilibrium speed.

Physics model: Three regions: phase current limited (I_fas = limit), battery current limited (I_batt = limit, solves R×I²+V_bemf×I=I_batt×V), and voltage limited (D=100%, I drops linearly).
