MapTiler Weather SDK 6종 기상 타일 오버레이:
- 바람/기온/강수/기압/레이더/구름 라디오 토글
- 3시간 단위 step 스냅 타임라인 + 드래그 실시간 seek
- 색상 범례, 배속 제어, 투명도 조절
- ServiceWorker 타일 캐시 (cache-first, 최대 2000장)
- SDK 시간 단위(epoch 초) 정합성 보장

Open-Meteo 수역별 기상 패널:
- 4개 수역 centroid 기반 해양/기상 데이터 5분 폴링
- 파고/풍속/수온/너울 카드 UI + 경고 하이라이트

- Mercator/Globe track-replay 레이어 충돌 및 setProps 레이스 해결
- track DTO 좌표/시간 정규화 + stale query 응답 무시
- 조회 직후 표시 안정화 및 기본 100x 자동재생 적용
- Global Track Replay 패널 초기 위치 조정 + 헤더 드래그 지원
- liveRenderer batch rendering + trackReplay store 기반 구조 반영
