 - Extended the Flanders map catalog and all-theme analysis so the four GRB
   products are usable on demand without browser-side external calls.
+- Prevented a single bounded municipality Dataset from being presented as
+  complete Flanders coverage; GRB cards remain `Op aanvraag` until the active
+  selection has produced its measured result.
 - Updated the provider registry to report the bounded GRB integration as
   configured while keeping the old generic import/fetch contract non-fetching
   and directing callers to the governed project endpoint.

 - Extended the Flanders map product catalog with the four GRB products and

+- Browser acceptance caught and closed a coverage-label defect: a newly
