+Rules:
+
+- Only vector/GeoJSON datasets are supported.
+- Coordinates are EPSG:4326 longitude/latitude.
+- Results are generated from persisted PostGIS `vector_features`, not from client-side map data.
+- The response is capped by `limit` and returns `truncated=true` when more matching rows exist.
