 The primary workflow is deliberately short: choose a municipality or the complete region, choose a data theme, drag a rectangle on the MapLibre map and read the resulting PostGIS evidence. Releasing the drag runs the active theme query and every other available theme query for the same EPSG:4326 bbox. The result panel shows selection area, exact intersection totals, active-theme density, source identity and bounded feature properties. Map rendering remains capped at 1,000 features while `total_feature_count` reports the exact database count.
 
+Every cross-theme result now names the measured quantity next to the value, so
+a station water level, mapped area and line length cannot appear as an
+unexplained bare number. Current vector selections download as GeoJSON,
+current raster analyses download as JSON and historical comparisons download
+as JSON with their complete timeline and provenance. After a successful
+analysis, compact next actions carry the same spatial context directly into
+`AI-vragen` or `Downloads`.
