+다음 작업: Phase 6 — 커스텀 명령어 + 설정 UI 고도화 + i18n
 차단 이슈: SoX 미설치, @nut-tree-fork/nut-js 포크 사용
 
+### Phase 3.5 구현 내용
+- HistoryPopup: Vanilla JS 팝업, 다크 카드(#242427), 앰버 악센트(#f25b29)
+- Ctrl+Shift+V 글로벌 단축키 → 커서 위치에 최근 10건 히스토리 팝업
+- Arrow↑↓ 선택, Enter 붙여넣기, 1-9 직접 선택, ESC 닫기
+- focusable: false → 활성 앱 포커스 유지
+- 2-phase 리사이즈, 등장/퇴장 애니메이션 (0.15s/0.1s)
+
 ### Phase 5 구현 내용
 - DB: better-sqlite3 + drizzle-orm (history/dictionary/stats 테이블, WAL 모드)
 - HistoryService: CRUD + 검색 + 통계 + 보존 정책(30일), 세션 완료 시 자동 이력 저장
