 - Exposed all four themes through the existing Flanders map selection flow.
   Provider calls remain backend-only and full-Flanders monolithic requests
   remain outside the bounded safety limits.
+- Prevented bounded municipality rasters from being labelled as complete
+  Flanders coverage; every governed thematic card remains `Op aanvraag` until
