+## Web Push 활성화 경계
+
+Gateway의 Android, iPhone과 Windows 브라우저 알림 기반은 포함하지만 기본값은
+`WEB_PUSH_ENABLED=false`입니다. 이 상태에서는 구독 버튼과 전송 worker가
+비활성이고, 알림 이벤트를 나중에 소급 전송할 backlog도 만들지 않습니다.
+
+활성화할 때만 VAPID key pair를 생성하여 공개키는
+`WEB_PUSH_VAPID_PUBLIC_KEY`, private key는 Git에서 제외한
+`WEB_PUSH_VAPID_PRIVATE_KEY_FILE`에 각각 넣고, 운영 연락처를
+`WEB_PUSH_VAPID_SUBJECT`의 `mailto:` 또는 HTTPS URL로 설정합니다. private key는
+runtime의 `/run/secrets/web_push_vapid_private_key`에 Compose secret으로만
+mount됩니다. 설정 후 `./scripts/check.sh`가 키 파일의 존재와 activation 필드를
+검증한 다음 runtime을 재생성해야 하며, 실제 활성화와 배포는 별도 운영 작업입니다.
