-### 🌟 전면 통합 및 주요 개선 완료 사항
-1. **설정 화면 4개 탭 One UI 8.5 전면 통일**:
-   - 기본설정, 알람설정, 부가기능, 근무관리 전체 탭에 24dp 라운드 카드(`bg_oneui_settings_card`) 및 36dp 스퀘어클 Soft-tint 아이콘(`bg_oneui_icon_container`) 시스템 완벽 적용
-   - 모든 드롭다운(Spinner)을 One UI 20dp 라운드 팝업(`bg_spinner_popup_oneui`), 12dp 알약 선택자 및 6dp 수직 오프셋으로 전면 통일
-2. **대한민국 법정 대체공휴일 수식 100% 정밀화**:
-   - 대통령령 관공서 공휴일 개정안을 반영하여 현충일(6/6), 신정(1/1) 제외 및 설날/추석 일요일 겹침, 단일 공휴일 토/일 겹침 수식 완벽 적용
-3. **이달의 누적 연장근무 복합 가산 수식**:
-   - 토요일 기본 특근(1일당 2h) + 달력 지정 '주맞'(+4h), '야맞'(+4h), '교육'(+2h) 자동 누적 정산
-4. **알람 그룹 순서 자동 정렬 & 6개 근무 지원**:
-   - 알람 목록 그룹 순서를 `주간(주) -> 석간(석) -> 야간(야) -> 주간 맞교대(주맞) -> 야간 맞교대(야맞) -> 기타`로 고정 정렬
-   - 그룹 마스터 스위치 및 아코디언 접기/펼치기 유지
-   - 알람 추가/수정 시 6개 근무타입(주/석/야/주맞/야맞/기타) 비율 맞춤 선택 지원
-5. **메인 달력 유체 모션 & 요약 칩 바**:
-   - 삼성 캘린더 `PathInterpolator(0.22, 1, 0.36, 1)` 기반 부드러운 수평 슬라이드 + 미세 페이드 + 미세 스케일 모션
-   - 상단 `주간 N일 | 석간 N일 | 야간 N일 | 연장 N시간` 실시간 요약 칩 바
-   - 하루 메모 3줄 직관 표시 및 달력 5줄 고정 / 6줄 스크롤 최적화
-   - 날짜 이동 모달 팝업 내부 취소/이동 버튼 및 근무 글자 20sp 대형화
-6. **배터리 최적화 4-Tier 다중 폴백**:
-   - Samsung Device Care (`com.samsung.android.lool`) 연동으로 100% 이동 보장
-7. **One UI 8.5 앱 업데이트 다이얼로그**:
-   - 32dp 라운드 카드, #007AFF 선명 블루 버튼, `bg_oneui_progressbar.xml` 실시간 퍼센트 채움 애니메이션
-8. **Android 14/15 호환 및 정식 서명키(release.jks) 유지**:
-   - `need to declare` 오류 완전 방지 및 덮어쓰기 업데이트 100% 지원"""
+### 🌟 주요 변경 및 개선 사항
+1. **📐 메인화면 상단 '교대링' 글자 위 빈 여백 공간 완전 제거 (`activity_main.xml`, `MainActivity.kt`)**:
+   - WindowInsets 및 헤더 레이아웃의 중복 패딩을 최적화하여 타이틀 상단 불필요한 공백을 완전히 없애고 시각적 안정감을 확보
+2. **📐 설정화면 상단 '설정' 타이틀 위 빈 여백 제거 (`activity_settings.xml`)**:
+   - `settingsHeader`의 과도한 상단 패딩(32dp)을 축소하여 상단 여백을 컴팩트하고 균형 있게 조정
+3. **🔄 인앱 APK 원클릭 다운로드 & 설치 업데이트 방식 복원 (`AppUpdateManager.kt`, `AndroidManifest.xml`)**:
+   - 앱 내에서 바로 업데이트 진행 상태를 확인하고 원클릭으로 즉시 설치할 수 있는 편리한 기존 인앱 업데이트 다이얼로그 방식으로 복원"""
