Villages drawn from where their societies actually sit: each cell is the Voronoi region of one village society points, merged by village. Shaded by effective micromarket — the tag when a village carries one (solid), otherwise the owner the last build computed for a village it included (lighter); villages the build left out are dimmed. Click a region or label to select, shift-click to add, shift-drag to box-select, then tag the selection — the cluster build reads those tags as overrides.
