Subject: [PATCH] New task
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI/CD 배포 시작됐습니다.

**핵심 변경:**
- 쿠폰 1개 = 캡차 요청 **정확히 1번** (재시도 완전 제거)
- OCR이 틀려도 바로 실패 처리 → TOO FREQUENT 원천 차단
- 쿠폰 간 5초 딜레이 유지

**트레이드오프:** OCR이 틀리면 해당 쿠폰은 실패로 표시됩니다. 그럴 경우 다시 "쿠폰 받기" 버튼 누르면 됩니다 (이미 성공한 쿠폰은 `alreadySucceeded` 로 스킵하고, 실패한 것만 재시도).
