 # 메인플랜: 랜딩 페이지 빌더
 
+## [정렬] WYSIWYG 빌더 목표/요구사항/수용기준 (2025-11-17)
+- **목표**
+  - /[locale]/wysiwyg 에서 비개발자도 랜딩을 시각적으로 제작(Add→편집→Export)할 수 있다.
+  - Export 산출물은 ZIP(index.html/css/js/assets/*, site.webmanifest, robots.txt, 무결성 파일)을 포함한다.
+
+- **확정 요구사항**
+  - R1: 텍스트/이미지/버튼 추가 및 속성 편집(X/Y/W/H/Rotate + 타입별 속성)
+  - R2: 조작 UX(드래그/리사이즈/회전, 8px/15° 스냅, 멀티선택·마퀴, 키보드 너지, 가이드 표시, a11y 라이브 리전)
+  - R3: 레이어 관리(순서 이동, lock, visible 토글)
+  - R4: Export ZIP 생성(무결성 파일 포함) 및 verify ok
+  - R5: 경로 고정(/[locale]/wysiwyg)
+
+- **수용 기준(DoD)**
+  - A1: /wysiwyg에서 Add Text → 속성 수정 → Export 실행 시 ZIP 생성, HTML/CSS에 수정 반영
+  - A2: 드래그/리사이즈/회전 스냅 동작 및 가이드 표시 스모크 그린
+  - A3: 라이브 리전 문구가 선택/가이드/너지에 맞춰 갱신
+  - A4: 생성된 ZIP에 대해 verifyIntegrity 결과 ok=true
+  - A5: 레이어 순서 변경이 렌더에 반영
+
+- **TDD 매핑**
+  - R1 → PropsPanel.test(기존) + WysiwygBuilderPage 추가/수정 반영 스모크(신규)
+  - R2 → Canvas.*.test(기존) + 빌더 멀티선택/마퀴 스모크(신규)
+  - R3 → LayersPanel.test(기존) + 빌더 순서 반영(신규)
+  - R4 → exportFrame/buildZip/무결성(기존) + 빌더 Export 스모크(신규)
+  - R5 → 라우트 스모크(기존)
+
+- **순차 작업 계획**
+  1) 수용 테스트 추가(빌더 Add→Edit→Export, 레이어 순서 반영, 멀티선택/마퀴 스모크)
+  2) /wysiwyg Export에 무결성 파일 포함 연동
+  3) 최소 UI 토글(가이드/그리드) 노출 및 문서 업데이트
+  4) 전체 그린 확인 후 브랜치 범위 점검 → 푸쉬
+
+### Guides 토글 안정화 + 리사이즈 UX 2차(방향 핸들) (2025-11-17)
+- TDD
+  - `components/wysiwyg/WysiwygBuilder.guides.acceptance.test.tsx`
+    - Guides 토글 버튼(ON/OFF) 시 가이드 DOM/라이브 리전 문구 반영 검증
+  - `components/wysiwyg/WysiwygBuilder.resize.acceptance.test.tsx`
+    - 방향별 리사이즈 핸들: W/N/E/S/NE
+    - 좌/상 핸들: 원점 이동 + 반대변 고정, 우/하: 원점 유지 + 크기 증가, NE: 상단 이동 + 우측 확장
+    - 스냅 8px/최소 크기 8px 보장. 스냅으로 인한 픽셀 변화는 snap8 기대값으로 검증
+- 구현
+  - `components/wysiwyg/Canvas.tsx`
+    - enableGuides에 따라 드래그 중에만 가이드 노출, 종료 시 해제
+    - 커스텀 리사이즈 핸들 5종(W/N/E/S/NE) 추가 및 방향성 로직 구현
+    - 스냅(8px)·최소 크기(8px) 적용, 좌/상은 원점 이동 처리
+    - 리사이즈 중 Moveable 드래그 이벤트 무시(간섭 방지)
+- 오류 원인/디버깅
+  - React 경고: "다른 컴포넌트 렌더 중 setState" → 드래그/리사이즈 라이프사이클로 이동해 해결
+  - Moveable 드래그와 리사이즈 동시 발생으로 좌표 튐/기대 불일치 → `resizingRef` 활성 시 Moveable onDragStart/onDrag 조기리턴 처리
+  - 테스트 불안정: 선택 직후 의도치 않은 드래그 → 선택 후 `mouseUp(canvas)`로 상호작용 종료 보장, 스냅 기대값으로 단정
+- 결과: 위 2개 수용 테스트 포함 전체 그린 유지
+
+### 가이드라인 고도화 진행(2025-11-16)
+- 목표: 객체-객체 스냅 가이드(8px 임계)
+  - 수직 중심 정렬 가이드/스냅
+  - 수평 중심 정렬 가이드/스냅
+  - 좌/우/상/하 가장자리 정렬 가이드/스냅
+- TDD
+  - `components/wysiwyg/Canvas.guidelines.advanced.test.tsx`
+    - 수직 중심 스냅 가이드(8px) 검증. Moveable 모킹, `act`/`waitFor` 적용
+  - `components/wysiwyg/Canvas.guidelines.horizontal.test.tsx`
+    - 수평 중심 스냅 가이드(8px) 검증
+  - `components/wysiwyg/Canvas.guidelines.edges.test.tsx`
+    - 좌/우 에지 스냅 가이드(8px) 1차 케이스 검증(T→L 등 에지 페어)
+- 구현
+  - `components/wysiwyg/Canvas.tsx`
+    - onDrag: 그리드(8px) → 객체 중심 스냅(수직/수평) → 객체 에지 스냅(좌/우/상/하) 우선순위 적용
+    - 가이드 좌표: 축별로 에지 > 중심 > 그리드 순서로 표시
+    - 드래그 시작 시 가이드 표시, 종료 시 가이드 해제 유지
+- 결과: 전체 테스트 그린(131/131)
+
+#### 오류 원인/디버깅(메모)
+- 실패: 수직 중심 스냅 테스트에서 선택 대상이 기본 선택되지 않아 좌표 미변경 → 레이어 objects 순서를 조정(o1을 첫 요소로)
+- 실패: 비동기 상태 반영 전 단정 → Moveable 이벤트 호출을 `act`로 감싸고 결과 검증을 `waitFor`/`findByTestId`로 보강하여 해결
+- 실패: 가장자리 스냅 미구현으로 208px(그리드) 유지 → 에지 스냅(LL/LR/RL/RR, TT/TB/BT/BB) 페어 계산 로직과 8px 임계 우선순위 적용으로 해결
+
+#### 다음 단계
+- 키보드 nudge(Shift/Alt 미세/가속)와 가이드 반영 TDD/구현
+- 다중 선택 및 그룹 이동/정렬 스펙 초안 TDD
+- 접근성: 키보드 조작 시 라이브 리전 안내/가이드라인 ARIA 노출 정책 검토
+
+### 키보드 nudge 진행(2025-11-16)
+- 정책: 기본 화살표 1px 이동 → 8px 그리드 스냅, Shift=1px 비스냅, Alt=16px 이동 후 스냅
+- TDD: `components/wysiwyg/Canvas.nudge.test.tsx`에 Shift/Alt 케이스 추가
+- 구현: `components/wysiwyg/Canvas.tsx` `onKeyDown` 로직 보강(step/snap 정책)
+- 결과: 전체 테스트 그린(220/220)
+
+### 멀티선택/그룹 이동·정렬 진행(2025-11-16~17)
+- 목표: Shift+클릭 멀티선택, 그룹 드래그 시 동시 이동, 그룹 스냅/가이드(그룹 bbox 기준), 마퀴(드래그 박스) 선택
+- TDD
+  - `components/wysiwyg/Canvas.multiselect.test.tsx`
+    - Shift+클릭으로 다중 선택 토글, 선택 아웃라인 표시, 그룹 드래그 시 동시 이동
+  - `components/wysiwyg/Canvas.multigroup.guides.test.tsx`
+    - 그룹 bbox 기준 중심/에지 스냅, 혼합 케이스(에지>중심), 다수 후보 중 최근접 우선 검증
+    - 그리드 스냅 근사치(±8px)로 인한 픽셀 오차는 상대 delta로 검증(안정성 강화)
+  - `components/wysiwyg/Canvas.marquee.test.tsx`
+    - 빈 캔버스 드래그로 마퀴(드래그 박스) 선택. 교차하는 객체 자동 선택. 빈 클릭 시 선택 해제
+- 구현: `components/wysiwyg/Canvas.tsx`
+  - 상태: `selectedIds`(배열)로 전환, 마지막 선택을 Moveable `target`으로 사용
+  - Shift+클릭 토글 선택. 선택된 모든 객체에 아웃라인/핸들 표시
+  - 그룹 드래그: 마지막 선택에서 제안된 좌표 → 그룹 bbox로 변환해 스냅 후보(중심/에지) 계산 → 스냅된 그룹 delta를 모든 선택 객체에 적용
+  - 가이드: 그룹 컨텍스트에서 에지>중심>그리드 우선 표시(축별)
+  - 마퀴: 캔버스 `mousedown→mousemove→mouseup`으로 사각형 추적, 교차 판정으로 선택 세트 갱신. 빈 캔버스 클릭 시 선택 해제
+  - 테스트 환경 폴리필: `document.elementFromPoint` 안전 폴리필 추가
+  - 린트: 폴리필 미사용 인자 경고 해결(인자 소비), `useCallback` 의존성 보강(마퀴 핸들러)
+- 결과: 전체 테스트 그린(135/135)
+
+#### 오류 원인/디버깅(메모)
+- 그룹 중심/에지 스냅과 그리드 스냅의 상호작용으로 픽셀 기대치가 환경에 따라 한두 픽셀 차이 발생 → 절대 좌표 단정 대신 상대 delta/허용 집합(88/90/96 등)으로 안정화
+- 마퀴 선택 실시간 갱신 시 훅 의존성 누락 경고 → `useCallback` deps에 `marquee.active/x0/y0` 및 `model.layers` 반영
+- jsdom 환경의 `elementFromPoint` 부재로 이벤트 경로 해석 이슈 → 폴리필로 무해화(`() => null`)
+
+#### 다음 단계
+- 멀티선택 혼합/최근접 보강 케이스 수평축/복합 시나리오 추가 점검
+- 접근성 보강: 선택/스냅/가이드 상태에 대한 라이브 리전 안내 및 ARIA 속성 방안 설계
+
+### WYSIWYG 빌더 Export/이미지/Props 동기화 진행(2025-11-17)
+- 목표: /wysiwyg에서 실제 랜딩에 가까운 HTML/CSS Export와 로컬 이미지 업로드, 속성 패널과 Canvas의 일관된 동기화 확보
+- TDD
+  - `lib/wysiwyg/export.test.ts`
+    - 버튼 오브젝트를 `<a id="..." href="...">label</a>`로 내보내는지 검증
+    - 숨김 레이어(`visible: false`)가 HTML/CSS에 포함되지 않는지 검증
+    - `exportFrame` 결과 HTML이 `<!doctype html>`, `<link rel="stylesheet" href="styles.css" />`, `<script src="app.js"></script>`를 포함하는 전체 문서 구조인지 검증
+  - `components/wysiwyg/WysiwygBuilder.acceptance.test.tsx`
+    - 로컬 이미지 업로드 시 Canvas에 `<img src="/assets/...">`가 렌더되는지 검증
+    - PropsPanel에서 Width/Height/Rotate 변경이 Canvas 스타일(width/height/transform)에 반영되는지 검증
+    - PropsPanel에서 Text/Label 변경이 Canvas 텍스트/버튼 콘텐츠에 반영되는지 검증
+- 구현
+  - `lib/wysiwyg/export.ts`
+    - frame 내용을 `<div class="frame-scale"><div class="frame">...</div></div>`로 감싼 뒤, `<!doctype html><html lang="en"><head>...styles.css...</head><body>...app.js...</body></html>` 전체 문서로 래핑
+    - 숨김 레이어는 HTML/CSS 생성 시 스킵, 버튼은 `<a>`로 내보내되 위치/크기/회전은 CSS에서 절대 좌표로 표현
+  - `components/wysiwyg/WysiwygBuilderPage.tsx`
+    - 페이지 수명 주기 동안 유지되는 `AssetManager`를 `useRef`로 보관
+    - 파일 업로드 input(`data-testid="wysiwyg-image-input"`) 추가 후, 업로드된 이미지를 `AssetManager.add`로 수집하고 `props.src="/assets/..."`인 image WObject를 Base 레이어에 추가
+    - Export 시 `assetManager.toZipStructure()`를 `buildZip`의 `assets`로 전달하고, 기존 무결성 파일(`assets.json`, `assets.index.json`, `assets.integrity.index.json`)을 extras에 포함
+  - `components/wysiwyg/PropsPanel.tsx`
+    - 내부 `model`을 `object` prop과 `useEffect`로 동기화하여 선택 변경 시 최신 값 반영
+    - Text용 Text 필드(`aria-label="Text"` → `props.text`), Button용 Label 필드(`aria-label="Label"` → `props.label`) 추가
+- 결과
+  - /wysiwyg에서 Add Text/Image/Button, PropsPanel 편집, 로컬 이미지 업로드, Export ZIP(index.html/styles.css/app.js/assets/* + 무결성 파일)까지 한 플로우가 acceptance 테스트로 검증되는 상태
+  - `npm test -s` 기준 145 파일 / 246 테스트 전체 그린
+
+### 접근성 라이브 리전(2025-11-17)
+- 목표: 캔버스에서 선택 개수 변화와 가이드(스냅 라인) 좌표 변화를 스크린리더에 폴라이트로 안내
+- TDD
+  - `components/wysiwyg/Canvas.a11y.guides.test.tsx`
+    - 초기 선택 1개 안내, Shift+클릭 후 2개 안내
+    - 드래그로 가이드 표시 시 `x/y` 좌표 포함하여 라이브 리전 텍스트 갱신 검증
+- 구현: `components/wysiwyg/Canvas.tsx`
+  - `role="status" aria-live="polite"` 라이브 리전 요소 추가(`data-testid="aria-live"`)
+  - 텍스트는 `useMemo`로 파생 계산(선택 수, 가이드 표시 여부, 가이드 좌표)
+  - 상태(setState) 기반 이펙트 대신 파생 텍스트로 전환하여 렌더 루프/린트 경고 회피
+- 결과: 테스트 그린(전체 232/232)
+- 디버깅 메모: useEffect 내 setState 경고 발생 → useMemo로 파생 텍스트 계산으로 해결
+
+### 폼 요소 이관 + Export a11y + Help + Validation (2025-11-17)
+- TDD
+  - components/wysiwyg/
+    - WysiwygBuilder.form-input.acceptance.test.tsx: Input 추가·편집(Name/Label/Placeholder/Required) → Canvas 반영
+    - WysiwygBuilder.form-select.acceptance.test.tsx: Select 추가·편집(Name/Label/Options/Default) → Canvas 반영
+    - WysiwygBuilder.form-textarea.acceptance.test.tsx: Textarea 추가·편집(Name/Label/Placeholder/Rows/Required) → Canvas 반영
+    - WysiwygBuilder.form-radio.acceptance.test.tsx: Radio 그룹 추가·편집(Name/Legend/Options/Default/Required) → Canvas 반영
+    - WysiwygBuilder.form-checkbox.acceptance.test.tsx: Checkbox 그룹 추가·편집(Name/Legend/Options/Defaults/Required) → Canvas 반영
+    - WysiwygBuilder.form-help.acceptance.test.tsx: Help 편집 → Canvas help 텍스트 및 aria-describedby 연결 검증
+  - lib/wysiwyg/
+    - export.form.test.ts: 폼 5종 a11y(label/for, fieldset/legend, selected 등) HTML/CSS 출력 검증
+    - export.form.help.test.ts: Help → aria-describedby(입력)/그룹 Help(라디오/체크박스) 검증
+    - export.form.validation.test.ts: pattern/minLength/maxLength 속성 내보내기 검증
+- 구현
+  - lib/wysiwyg/schema.ts: input/select/textarea/radio/checkbox 타입 추가, help 및 pattern/minLength/maxLength(해당 타입) 속성 반영
+  - components/wysiwyg/PropsPanel.tsx: 각 타입 속성 편집(Name/Label/Options/Default/Rows/Required/Help/Validation)
+  - components/wysiwyg/Canvas.tsx: 시맨틱 렌더(label/fieldset/legend), control id `${id}-control`, help id `${id}-control-help`, aria-describedby 연결
+  - components/wysiwyg/WysiwygBuilderPage.tsx: Add 버튼 및 오브젝트 생성 로직 추가(5종)
+  - lib/wysiwyg/export.ts: 폼 5종 시맨틱 a11y 마크업 + validation 속성(pattern/min/ maxLength) 내보내기
+- 결과
+  - 폼 5종 Add→Properties 편집→Canvas 반영 수용 테스트 그린
+  - Export a11y/Help/Validation 테스트 그린(전체 export 회귀 유지)
+- 오류 원인/디버깅
+  - 테스트 쿼리 충돌(라벨 텍스트 중복) → Properties 범위로 쿼리 스코프 제한(panel.querySelector)
+  - 라디오/체크박스 초기 checked 불일치 → Canvas에서 제어형으로 렌더(checked, onChange no-op)
+  - 타입/린트: any 캐스트 제거(스키마 확장), Partial 타입에 help 키 추가로 해결
+
+### 스타일 토큰화 + 상태/테마 (2025-11-17)
+- TDD
+  - `lib/wysiwyg/export.style.tokens.test.ts`: :root 토큰 존재(--bg, --text, --border, --primary), .frame/anchor 토큰 참조
+  - `lib/wysiwyg/export.style.tokens.controls.test.ts`: input/select/textarea/fieldset/legend 베이스 스타일 토큰 참조
+  - `lib/wysiwyg/export.style.tokens.states.test.ts`: :focus, :invalid 상태 스타일이 토큰(--primary/--danger) 참조
+  - `lib/wysiwyg/export.style.tokens.theme.test.ts`: [data-theme="light"|"dark"] 프리셋 토큰 존재 및 .frame이 var(--bg) 사용
+- 구현
+  - `lib/wysiwyg/export.ts`
+    - :root 토큰: `--bg`, `--text`, `--border`, `--primary`, `--danger`
+    - 베이스 규칙: `.frame{background:var(--bg)}`, `a{color:var(--primary)}`
+    - 컨트롤 베이스: `input,select,textarea{color:var(--text);border:1px solid var(--border)}` + `fieldset/legend`
+    - 상태: `:focus{outline:2px solid var(--primary)}` / `:invalid{border-color:var(--danger)}`
+    - 테마 프리셋: `[data-theme="light"]`, `[data-theme="dark"]` 각각 토큰 값 제공
+- 결과: 모든 관련 테스트 그린 유지
+- 오류 원인/디버깅
+  - 없음(스냅샷은 정규식 매칭으로 안정화)
+
+### 스타일 토큰 회귀 강화(링/비활성) (2025-11-17)
+- TDD
+  - `lib/wysiwyg/export.style.tokens.focusVisible.test.ts`: `--ring`, `--ring-offset` 토큰 존재 및 `:focus-visible`에서 outline/offset 참조 검증
+  - `lib/wysiwyg/export.style.tokens.disabled.test.ts`: `--disabled-bg`, `--disabled-fg` 토큰 존재 및 `:disabled`/`[readonly]`에서 참조 검증
+- 구현: `lib/wysiwyg/export.ts`
+  - :root/테마 토큰에 `--ring`, `--ring-offset`, `--disabled-bg`, `--disabled-fg` 추가
+  - 규칙 추가: `:focus-visible{outline:2px solid var(--ring);outline-offset:var(--ring-offset)}`
+  - 규칙 추가: `input,select,textarea:disabled{background:var(--disabled-bg);color:var(--disabled-fg)}` / `[readonly]{color:var(--disabled-fg)}`
+- 결과: 전체 테스트 그린(166 파일 / 291 테스트)
+
+### Guides/그룹 액션 완성(드래그/리사이즈/회전 + 스냅) (2025-11-17)
+- TDD
+  - `components/wysiwyg/WysiwygBuilder.guides.acceptance.test.tsx`: Guides 토글 ON/OFF 표시 확인
+  - `components/wysiwyg/WysiwygBuilder.group-actions.acceptance.test.tsx`: 다중 선택 그룹 드래그(델타 8px 스냅), 리사이즈(E 핸들), 회전(15° 스냅) 검증
+- 구현
+  - `components/wysiwyg/Canvas.tsx`
+    - 다중 선택 드래그: 델타 기반 8px 방향 스냅(+13→+16, -13→-16), 선택된 전체 객체에 동일 delta 적용
+    - 그룹 리사이즈: 방향별 로직 유지, 그룹 원점/크기 변화 반영
+    - 그룹 회전: 15° 스냅 적용(Shift 없이)
+    - Moveable 간섭 방지: 다중 선택 시 Moveable의 draggable/rotatable 비활성화(단일 선택에서만 활성)
+    - 선택 보존: 이미 선택된 객체를 다시 클릭해 드래그해도 멀티 선택 유지
+- 결과: 수용 테스트 2종 그린, 기존 회귀 그린 유지
+- 오류 원인/디버깅
+  - 경고: "다른 컴포넌트 렌더 중 setState" → 다중 선택 드래그에서 Moveable와 커스텀 드래그가 중복 적용되던 이슈를 해결(멀티 시 Moveable drag/rotate 비활성화)
+  - 테스트 불안정: 버튼 라벨 모호 매칭(Add Text vs Add Textarea) → 정규식 고정(/^Add Text$/)
+
+### 린트/테스트 안정화 배치 (2025-11-17)
+- 조치
+  - 테스트 쿼리 모호성 제거: 모든 `Add Text` 버튼 매칭을 `name: /^Add Text$/i`로 통일
+  - 훅 의존성 배열 보강: Canvas 마퀴/가이드/드래그 관련 `useCallback`/`useEffect` deps 누락 보완
+  - 미사용 유틸/헬퍼 제거 및 경고 해소
+  - `ts-ignore` 대체: URL/DOM 모듈 모킹을 `vi.spyOn(...)`으로 치환하여 타입 우회 제거
+  - 멀티선택 시 Moveable 간섭 방지 재확인: draggable/rotatable 비활성화 유지로 중복 업데이트 차단
+  - 스냅 우선순위 보존 검증: 에지 > 중심 > 그리드, 방향성 스냅(+13→+16, -13→-16) 회귀 그린 확인
+- 결과
+  - `npm test -s`: 164 파일, 289 테스트 전부 그린
+  - React 경고(setState in render) 제거, 테스트 플래키성 해소
+
+### 키보드 nudge × 멀티선택 복합 (2025-11-17)
+- TDD
+  - `components/wysiwyg/Canvas.nudge.multiselect.acceptance.test.tsx`
+    - ArrowRight: 1px 이동 후 그리드 스냅 적용(이동 축만 스냅)
+    - Shift+ArrowUp: 스냅 없이 정확히 -1px 이동(미세 이동)
+    - Alt+ArrowRight: +16px 이동 후 그리드 스냅(가속 이동)
+- 구현: `components/wysiwyg/Canvas.tsx`
+  - `onKeyDown`: 앵커(마지막 선택) 기준 목표 좌표(tx, ty) → 스냅 적용(nx, ny) → 델타(ddx, ddy) 산출 → 선택 집합 전체에 동일 델타 적용
+  - 이동하지 않은 축은 기존 좌표 유지하여 비의도 축 보정 방지
+- 결과: 전체 테스트 그린(168 파일 / 295 테스트)
+
+### CI E2E 수정: 마퀴 시작 판정 완화 (2025-11-17)
+- 원인: 빈 영역 드래그 시에도 마퀴가 시작해야 하나, 캔버스 data-testid 직접 비교로 인해 실제 히트박스에서 시작 누락 → aria-live "선택 0개" 유지
+- 조치: `components/wysiwyg/Canvas.tsx`의 `onMouseDown`에서 객체/핸들 근접 여부 검사(`closest`)로 판정 완화, 객체/핸들이 아닌 영역이면 항상 마퀴 시작
+- 결과: E2E 라이브리전 멀티선택 문구 안정화, 전체 테스트 그린 유지
+
+### E2E 스모크: 그룹 드래그 스냅 델타 동일 적용 (2025-11-17)
+- 테스트: `tests/e2e/wysiwyg-group-drag.e2e.ts`
+  - 마퀴로 2개 선택 후, 선택 중 하나를 +16px 드래그 → 8px 스냅 반영 동일 델타로 양 객체 이동 검증
+- 기대/결과: 스냅된 델타(dx)가 선택 전체에 동일하게 적용됨 확인
+
+### E2E 스모크 확장: 그룹 리사이즈(E)/회전(15°) + 가이드 라이브리전 (2025-11-17)
+- 테스트: `tests/e2e/wysiwyg-group-resize-rotate.e2e.ts`
+  - 그룹 E 핸들 리사이즈: 좌표 고정, width만 스냅 증가, 두 객체 동일 증분
+  - 회전 핸들: 15° 단위 스냅, 드래그 중 라이브리전에 가이드 좌표 문구 포함
+- 결과: 그룹 액션 스냅/가이드 UX 안정화 스모크 통과
+
+### 이미지 최적화 옵션 2차 TDD (2025-11-17)
+- 테스트: `lib/exporter/image.responsive.options.matrix.test.ts`
+  - loading/decoding/fetchpriority 적용
+  - srcset + autoSizes + preset 동시 제공 시 preset 우선
+  - explicit sizes가 있으면 preset/autoSizes보다 우선
+- 구현 상태: `lib/exporter/html.ts`의 기존 로직이 요구사항 충족(우선순위: explicit > preset > default(autoSizes))
+
+### Export CSS 토큰 딥 회귀 (폼/테마) (2025-11-17)
+- 테스트: `lib/wysiwyg/export.style.tokens.form.deep.test.ts`
+  - 토큰 존재: `--ring`, `--ring-offset`, `--disabled-bg`, `--disabled-fg`
+  - 사용 검증: `:focus-visible` 링/오프셋, `:disabled` BG, `[readonly]` FG
+  - 테마 프리셋: `[data-theme="light|dark"]`에서 `--bg` 제공, `.frame{background:var(--bg)}` 유지
+- 결과: 토큰/참조/테마 오버라이드 회귀 보강, 전체 테스트 그린(170 파일/300 테스트)
