SPAN — rope two roads together. Move one, both answer.
`span`: tap road A, tap road B — the rope spans the distance.
Tap the gold ring: SYNCED (1:1, B follows A) or MIRRORED (−1:1, B opposes A).
Rigid law: the sync is exact. The rope stays taut and true.
`unspan` cuts every span — roads move independently again.
