 Regional VMM provisioning creates one scenario raster per municipality Area.
-The explorer therefore shows only the flood scenarios whose `area_id` matches
-the active work area. This avoids presenting a Mol scenario while the map is
-focused on another municipality. The region-wide Area remains the navigation
-context; municipality Areas are the analysis scope for flood rasters because
-the public WCS and raster cell limits make one monolithic Kempen raster
-operationally unsafe.
+For a municipality the explorer still uses only that exact Area-linked file.
+For the complete Kempen Area it presents the 28 VMM and DHMV partitions as one
+logical map layer, deduplicates VMM into twelve scenario choices and renders
+every matching MapLibre image partition. A drawn rectangle is sent to the
+partition endpoint, which opens only intersecting files and calculates exact
+combined cell statistics. A monolithic full-region 5 m calculation remains
+disabled because it exceeds the governed raster-cell limit; users draw a
+bounded rectangle without first choosing a municipality.
