Geofences

1. Draw with the polygon tool on the map. A smaller shape drawn inside it becomes a no-go pocket (a pond, a terrace).
2. Name it, pick a type and save it as a draft.
3. Enable it — carts pick it up within about 20 seconds. Any number of fences can be on at once.
4. Brass dots are live carts: park one on a corner and click its dot while drawing to place the point exactly.

A cart is in bounds inside any enabled allowed fence and outside every no-go zone. Enabled fences can't be reshaped — Edit saves a new draft you enable in its place.
