On a Card
A readout walking the series. The rule steps from point to point while the dot glides along the line itself through offset-path — so the dot is always on the curve and never between two points. The chart is a size container, so --wm-span can be written in cqw and the rule's steps land on the points at any card width: six points, 57.6 of 320 units apart, make a span of 6 × 18% = 108cqw.
The class is wm wm-crosshair-follow — the first half is the marker the trigger and reduced-motion rules hook into, the second is the effect.
