Aggregate regional bathymetry partitions

frontend/README.md

@@ -657,3 +657,10 @@ Municipality partitions remain hidden for a regional Area until their backend
 manifest reports complete coverage. The Sources workspace lists MDK North Sea
 as read-only probe-only and SPW Walloon bathymetry as planned until bounded
 raster/download acquisition is operational.
+
+For a complete regional manifest, the theme card totals all data-bearing
+municipality partitions instead of displaying one representative partition.
+A regional rectangle or full-Area analysis calls the partitioned backend
+selection and draws only its bounded GeoJSON result. Switching to a
+municipality automatically returns to the exact single-Area Dataset. Regional
+downloads are recomputed server-side through the same manifest-aware path.
