+When governed VMM scenarios are present, the Map explorer adds a separate
+`Overstroming` theme. It is deliberately not merged into `Water`: the latter
+describes persisted water surfaces and watercourse lengths, while the former
+is modeled flood hazard. A scenario selector keeps pluvial/fluvial,
+T10/T100/T1000 and current/2050 conditions visible before analysis. The
+persisted depth raster is shown through the existing MapLibre image-overlay
+pattern and a rectangle returns scenario-bound hectare/depth metrics. Raster
+GeoJSON export stays disabled. The UI never labels the maximum-depth area
+integral as current, permanent or concurrent water volume.
