How do the edges work? Does the site provide them at the start, or do neighbours come to a consensus on what their edges look like?

New tiles receive edges from their neighbours, and they must make sure they blend in correctly.

When a tile is uploaded back, we discard the edges that would overlap existing tiles and present that to the curator to confirm the tile is correct.
