-The persisted `Kempen Regional Workbench` is the automatic operational data context. Its current GRB layers are loaded once for the complete official 28-municipality Vlaamse vervoerregio; the operator chooses Mol, another municipality or the complete region as a spatial work-area filter. The primary map no longer asks the user to choose a technical project or region before data becomes usable. Mol remains the primary validation and historical-data focus, while explicit project selection stays available under advanced management.
+The persisted `Kempen Regional Workbench` is the automatic operational data context. Its datasets are loaded once for the complete official 28-municipality Vlaamse vervoerregio; the operator chooses Mol, another municipality or the complete region as a spatial work-area filter. The primary map no longer asks the user to choose a technical project or region before data becomes usable. Regional population and modern forest snapshots use the same current/evolution flow as Mol, while explicit project selection stays available under advanced management.
 
 The user-facing shell is task based: `Kaart`, `Bronnen`, `Kwaliteit`, `Beeldanalyse`, `Downloads`, `Status` and `Beheer`. Internal benchmark projects, raw dataset metadata, provider capabilities, model registry details and QA evidence remain accessible through labelled advanced disclosures instead of competing with the normal workflow.
