On a Drop Zone
Four repeating gradients as the border, moved by exactly one dash period so the loop has no seam. A real dashed border cannot animate, so the Drop Zone’s own border is set to transparent and this draws over it.
The class is wm wm-marching-ants — the first half is the marker the trigger and reduced-motion rules hook into, the second is the effect.
