+### 🎨 NaverMapView 채널별 마커 색상 (v0.1.60)
+- GoogleMapView와 동일 팔레트 (amber/blue/green/pink/purple/red/teal/yellow)
+- 식당의 첫 채널 기준 색상, activeChannel 있으면 그 채널 우선

 ### ⚡ NaverMapView SDK 네이티브 마커 + InfoWindow (v0.1.59)
 - 마커를 React `absolute div` overlay → `naver.maps.Marker` 네이티브로 교체
   - 줌/팬 시 SDK가 GPU 최적화, 매 frame React 리렌더링 없음 → 랙 해소
