 - 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.
+- `limit` is bounded to `1..1000`. Municipality-scale clients must page spatially by viewport instead of requesting an unbounded municipality FeatureCollection.
+- The Map workspace uses this existing endpoint for vector datasets above 5,000 features. It starts delivery at zoom level 14, debounces `moveend` requests and explicitly reports `truncated=true` as a request to zoom further in. This is a client delivery policy, not a second API or persistence path.
