Overview
Node abstracts path routing to pure geometry: connect designated nodes with non‑crossing lines under limited bend allowances. The grid rewards keeping a backbone corridor open while threading shorter connections around the edges. Plan two links ahead: draw the route that unlocks more future straights, not the one that barely fits now. If a path snakes through central space, undo and relocate it to the perimeter to preserve the trunk. Bends are expensive—minimize them and let straight segments carry the layout. As structure settles, the map reads elegant: a clear trunk, neat locals, and no lines fighting each other. The last link clicks because every earlier choice protected corridors instead of consuming them.
