+**Modals** (`modal.js` + modal HTML in `index.html`):
+- All modal cancel/close buttons use `.modal-close` and `btn-ghost`.
+- All modal primary buttons use `.modal-action`, `btn-success`, and the text `실행`.
+- `Escape` triggers the active modal's `.modal-close`; `Enter` triggers its `.modal-action`.
+- `Tab` / `Shift+Tab` is trapped inside the active modal.
+- Modal titles use `.modal-titlebar`; warning/danger variants are `.modal-titlebar-warning` and `.modal-titlebar-danger`.
+- Rename confirm uses the same modal for selected-only and all-image rename. The visible title switches between "선택된 이미지 저장" and "전체 이미지 저장"; selected-only mode also shows "선택된 파일들만 저장합니다".

 **Thumbnail loading:** `IntersectionObserver` with `rootMargin: '400px 0px'` — lazy load as cards enter viewport. `entry.target.isConnected` 체크로 폴더 전환 중 스탈 카드 방지. Drag reorder remaps card elements via `card.dataset.filepath` to avoid re-fetching.

 **Sidebar tree** (`file-explorer.js`): Lazy-load 자식 폴더. 접근 불가 폴더는 `null` 반환 → "접근 불가" 표시. 행 클릭 시 항상 펼침, 화살표 클릭 시 토글.
