   2. **Grid Row & Item Context Actions (Table Row Actions)**: Dedicated to **Single-Row CRUD & Processing** (e.g., `✏️ 수정`, `🗑️ 삭제`, `🔍 상세보기`, `▶ 재처리`). Placed in a pinned right column or explicit context menu; never placed in page top toolbar.
   3. **Multi-Selection Batch Toolbar (Grid Top/Bottom Selection Bar)**: Activated conditionally upon multi-row selection for **Bulk Actions** (e.g., `선택 일괄 승인(3)`, `선택 일괄 삭제`).

Static text ("불러오는 중...") or empty screen placeholders during loading states are STRICTLY PROHIBITED.

 ### Anti-Patterns (금지)
 
 - ❌ "일단 만들고 나중에 리팩터" → Feature 초기부터 정공법
 - ❌ "페이지에 창 스크롤바가 생기게 방치" → 대시보드 제외 모든 업무 화면은 Viewport-Fit Zero-Scroll 필수
 - ❌ "버튼 위치 난잡 배치" → 상단 우측(페이지/배치), 행 내부(개별 CRUD), 선택바(일괄), 폼 푸터(저장/취소) 표준 무시 금지
+- ❌ "로딩 시 '불러오는 중...' 텍스트 방치" → 반드시 레이아웃 맞춤형 애니메이션 스켈레톤(SkeletonLoader) 적용 필수
 - ❌ "혹시 필요할까봐 추상화" → Necessity-driven만
 - ❌ SELECT * / Generic Repository → Explicit columns, explicit logic
 - ❌ "이건 작은 변경이라 테스트 스킵" → 모든 경로 characterize
