Production smoke test on 2026-05-15: /api/gs25/stores?keyword=강남 returns HTTP 200 but zero stores, and /api/gs25/inventory?keyword=오감자&storeKeyword=강남 can fail while itemCode+lat/lng works. User impact: vague requests like '오감자 GS25 강남 재고' need too much manual parameter work. Acceptance: keyword store lookup produces useful nearby stores or inventory flow falls back through product search/geocoding consistently, with regression tests.
