 - `GET /api/v1/cities/?search=` — search cities by name (`apps/locations/views.py`); previously no text search existed.
 - `GET /api/v1/neighborhoods/?search=` — search neighborhoods by neighborhood name or city name, alongside the existing `city` UUID filter (`apps/locations/views.py`).
 - `GET /api/v1/stores/` now returns `phone_number` in the list (previously only on the single-store detail view) and a `distance_km` field, populated whenever `lat`/`lng` are passed (`apps/stores/serializers.py`).
+- Store `latitude`/`longitude` now come back on every store response — list, retrieve, and the seller's own store (`GET`/`PATCH`/`POST /api/v1/seller/store/`) — derived from `Store.location` via new `Store.latitude`/`Store.longitude` properties (`apps/stores/models.py`, `apps/stores/serializers.py`). Previously they were write-only on the seller serializer and absent everywhere else.
 - Test coverage for `StoreViewSet` list filtering (`apps/stores/tests/test_store_list.py`) — previously untested.
 - Test coverage for `ProductViewSet` list filtering (`apps/catalog/tests/test_product_list.py`) — previously untested.
 - Test coverage for `CityViewSet`/`NeighborhoodViewSet` list filtering (`apps/locations/tests/test_location_list.py`) — previously untested.
