+## Area-aware map layer selection
+
+Map themes can have both a complete regional Dataset and a smaller exact-Area
+snapshot from the same official source. The workbench prefers the Dataset whose
+`area_id` exactly matches the selected Area; when no exact snapshot exists, the
+regional Dataset remains available and the backend clips metrics and map output
+to the selected municipality or drawn rectangle. The Sources workspace reports
+overlapping BWK area snapshots as separate coverages and does not sum their
+feature counts as if they were disjoint observations.
