Why does a reverse hitch?
Press Play. Top is the bug: a CSS tween that stops and starts over. Bottom is the fix: a spring that turns. Don’t ship the top for a reverse. They look the same until you change your mind mid-move.
How long is shared. Both lanes take that time if you let them finish. Curve is only the top. Settle is only the bottom. Drag a target and the top freezes while the bottom chases.
