-# 메인플랜: 랜딩 페이지 빌더
-
-## 목표
-- 비개발자도 사용 가능한 단일 페이지 랜딩 페이지 빌더.
-- 결과물: 정적 ZIP(HTML/CSS/JS) 다운로드. 이미지: 외부 URL 또는 로컬 업로드(서버 저장 없음, ZIP에 패키징). 폰트는 외부 CDN 허용.
-- 폼: 다양한 필드 타입(파일 업로드 제외), 커스텀 name, action URL 설정. action 미지정 시 Google Sheets 저장.
-- 다국어 지원(i18n), 접근성 준수, SEO/OG 메타, 분석 스니펫 삽입.
-
-## 확정 요구사항
-- 단일 페이지 기준.
-- 이미지: 외부 URL 또는 로컬 업로드 허용(서버 저장 없음, ZIP 패키징). CDN 허용(예: Google Fonts 등).
-- 폼 필드 타입: 텍스트/이메일/전화/셀렉트/라디오/체크박스/텍스트에어리어/날짜 등(파일 업로드는 추후).
-- 검증 규칙 필요. 스팸 방지: 기본(honeypot, 제출지연 타임스탬프).
-- 제출 경로: 1) 사용자가 action URL 지정 → 2) 미지정 시 Google Sheets.
-  - 기본: Google Apps Script 웹앱 템플릿 가이드 제공(사용자 배포 URL 사용)。
-  - 대안: 서비스계정 + Google Sheets API(선택).
-- 다국어 지원 필요. 접근성 준수. SEO/OG 포함. 분석 스니펫 삽입 기능 필요.
-- 스택: React 기반. Next.js(App Router) + TS + Tailwind + shadcn/ui 권장.
-
-## 아키텍처 개요
-- 빌더 앱: Next.js(App Router, TS), Tailwind, shadcn/ui, dnd-kit, Zustand.
-- 도메인 스키마: Page → Section[] → Block[] → Form(fields, validation, actionUrl) → Theme.
-- 에셋 매니저: 사용자가 업로드한 이미지를 메모리/브라우저에서 관리, 파일명 해싱 후 `assets/` 경로로 참조 재작성.
-- HTML Exporter: JSON 스키마 → 정적 HTML/CSS/JS 생성. 로컬 업로드 이미지는 `assets/`로 참조, 외부 URL은 그대로 유지.
-- 제출 경로: action 사용 또는 Google Sheets(기본 Apps Script 템플릿 제공).
-- i18n: next-intl. a11y: Testing Library + axe-core 스모크. SEO/OG 메타 생성.
-- 내보내기: ZIP(브라우저 JSZip 우선). 필요 시 서버(API Route) 대안 제공. 로컬 업로드 이미지는 ZIP 내 `assets/` 폴더에 파일로 포함.
-
-## UI/UX 리디자인 계획(합의안)
-- **정보 구조(3패널)**
-  - 좌: 컴포넌트 패널(Hero/FAQ/CTA + Form 프리셋)
-  - 중: 캔버스(dnd-kit, 섹션/필드 배치·정렬·삭제)
-  - 우: 인스펙터(선택 요소 속성/검증/스타일 편집)
-- **상단 툴바**: 언어, 테마, 프리셋, Export ZIP
-- **프리뷰**: 실시간 렌더, 반응형 뷰포트 토글
-- **계약 고정**: 스키마(섹션/폼/검증), 상태 인터페이스, Exporter 입·출력
-
-### 단계별 TDD 진행
-1) 레이아웃 스캐폴딩(shadcn/ui) + 접근성 라벨링 테스트
-2) dnd 캔버스 1차: 섹션 드래그 정렬/삭제 테스트 → 최소 구현
-3) 인스펙터 1차: 선택 섹션/필드 기본 속성 편집 테스트 → 연동
-4) 컴포넌트 패널: 카드 추가(섹션/필드 프리셋) 테스트 → 드래그 추가
-5) 프리뷰 강화: 실시간 반영/뷰포트 토글 스모크 테스트
-
-### 현재 상태(MVP)
-- 섹션 추가/삭제, 폼 필드 구성(옵션/필수/패턴/최대길이), i18n, ZIP Export, 로컬 에셋 포함 동작 확인

-

-- 섹션 식별: `aria-labelledby` + 섹션 헤딩 id(features/testimonials/faq)

-  - Node 20 + `npm ci`
-  - Vitest 실행 → Playwright 브라우저 설치(`npx playwright install --with-deps`) → E2E 실행
-
-### CI 최종 점검
-- main/master 브랜치 푸시/PR 시 워크플로 자동 실행 확인
-- 새로 추가된 테스트(헤딩 레벨 전수, 색/폰트 스모크) CI 통합 확인
-- 작업 브랜치 푸시 완료: `chore/ci-verify-a11y-headings` (원격: origin)
-- PR 생성 및 Actions 결과 기록 예정(base: main)
-- CI verification note: 러너 온라인 이후, 사소 변경으로 CI 트리거 검증 예정
-  - CI rerun: 워크플로 재실행용 ping 커밋
-
-#### 결과: CI 통과 (self-hosted Gitea Actions)
-- PR: https://gitea.jaybe.dev/jaybe/landing-builder/pulls/2
-- 러너: self-hosted, labels: [macos, host]
-- 테스트: Unit/Component + E2E 총 7/7 green
-- 수정 요약(E2E 포커스):
-  - 초기 포커스 선점 방지: `body` 클릭으로 포커스 부여
-  - 스킵링크 등 선행 포커서블 회피: Desktop 버튼에 명시적 `focus()`
-  - 키보드 시나리오: Tab → Mobile 포커스 확인 → Space로 토글 → Shift+Tab → Enter
-
-#### 머지 상태
-- 머지 방식: Squash and merge
-- 브랜치 정리: `feat/ci-verify-run` 삭제 완료
-
-### 다음 스프린트 후보 과제
-- Exporter 회귀 스냅샷 보강(폼 토큰/검증 토큰 범위 확대)
-- 인스펙터 신규 섹션 추가 시 a11y 베이스라인 재사용 가이드 마련
-- 버튼 네이밍 일관성 전수 스캔 스모크 범위 확대

-## 릴리스
-### v0.1.0
-- CI 검증 완료(Self-hosted Gitea runner, labels: [macos, host])
-- E2E 안정화: 초기 포커스 이슈 제거(Desktop 명시 focus), 스킵링크 고려
-- Exporter(Form) a11y: helptext ↔ aria-describedby, id/htmlFor 연결, 라디오 fieldset 설명 연결
-- i18n: en/ko 중첩 구조, 누락 키 보강(builder.action.*, builder.form.*)
-- next-intl: 기본 timeZone=Asia/Seoul 설정으로 ENVIRONMENT_FALLBACK 경고 제거
-- 태그: v0.1.0
-
-## 접근성 베이스라인 가이드(신규 섹션/인스펙터 적용 규칙)
-- **레이블 연결**: 모든 입력은 `id=ins-...` 또는 `id=field-...` 부여, `<label for>`로 연결
-- **헬프텍스트 연결**: 헬프 요소 `id=...-help` 생성, 입력에 `aria-describedby`로 연결
-- **라디오 그룹**: 개별 `<input>` 대신 `<fieldset>`에 `aria-describedby` 적용, 옵션은 `id/htmlFor`로 연결
-- **버튼 네이밍**: 보이는 텍스트 또는 `aria-label`로 안정적 접근 가능한 이름 제공
-- **키보드 활성화**: Enter/Space 활성(onClick와 동일 동작), `focus-visible` 스타일 유지
-- **스킵링크**: `<a class="skip-link">` 제공, 포커스 시 화면 내 표시
-- **헤딩 레벨**: hero=h1, 1뎁스 섹션=h2, FAQ 항목=h3 일관성 유지
-- **미리보기 토글**: 토글 버튼에 `aria-pressed`, `aria-controls`, `aria-describedby` 연결
-- **i18n 키**: 중첩 객체 구조, 신규 키 추가 시 en/ko 동시 보강
-- **테스트 원칙**: TDD로 유닛/컴포넌트/E2E 및 스냅샷 추가. 포커스/ARIA/토큰 스모크 포함
-
-### 적용 가이드(신규 섹션 추가 시)
-- **1) 섹션 구현**: `<section class="<name>" aria-labelledby="<name>-heading">`와 `<h2 id="<name>-heading">` 구성
-- **2) 인스펙터 입력**: `id=ins-...`, `<label for>`, 헬프텍스트 `...-help` + `aria-describedby` 연결
-- **3) Exporter 반영**: 섹션 렌더 함수에 위 구조/속성 부여
-- **4) 테스트 추가**:
-  - 공통 템플릿 사용: `lib/exporter/testUtils/sectionA11y.ts` → `assertSectionA11y(html)`
-  - 샘플: `lib/exporter/sectionA11y.template.test.ts` 참고하여 새 섹션 추가해 검증
-  - 필요 시 개별 스냅샷/스모크: 헤딩/ARIA/키보드/토큰 추가 검증
-
-## 다음 단계(E2E 초안)
-- 시나리오: 섹션 추가(Hero/FAQ/Features/Testimonials/CTA) → 인스펙터 편집 → Export ZIP 생성 → HTML 메타/섹션/폼 렌더 확인
-- 환경: Playwright
-- 체크리스트: 
-  - 섹션 추가/정렬/삭제 동작
-  - 인스펙터 편집 반영(미리보기/Export HTML)
-  - i18n 라벨 안정성(data-testid 사용)
-  - a11y 스모크 무결성 유지
-
-## TDD 전략
-- 각 기능 단위로: 실패 테스트 작성 → 최소 구현 → 리팩터 → 커버리지 확인.
-- 단위: Vitest + Testing Library + jsdom. E2E: Playwright.
-- 접근성: axe-core 스모크 테스트.
-
-## 작업 보드(요약)
-- 스키마/도메인(Zod)
-- HTML Exporter
-- 에셋 매니저
-- 폼 엔진
-- Sheets 연동
-- 빌더 UI
-- 내보내기 ZIP
-- i18n
-- a11y/SEO/OG/Analytics

-## 오류/버그 기록
-- [2025-11-13 22:55] BuilderClientPage 렌더 중 ref 접근 경고 / useRef.current를 렌더 중 참조하여 ESLint 경고 발생 / FormBuilderPanel 통합 시 `useRef(createFormStore())` 사용 / `useMemo(() => createFormStore(), [])`로 스토어 인스턴스 고정하고 `useSyncExternalStore`에 직접 주입하여 해결 / 렌더 중 ref 접근 금지 원칙 재확인
-- [2025-11-14 09:35] Vitest 로그에서 i18n 누락 메시지 경고 확인(en: `builder.action.addSelect/addRadio`, `builder.form.actionUrl/honeypot/minSeconds`) → `messages/en.json`에 키 존재 여부 점검 및 누락 보완 후 재실행, 모든 테스트 그린 유지
-- [2025-11-14 09:45] 프리뷰 텍스트 매칭 불안정으로 테스트 실패 → `data-testid` 기반 안정화(`preview-seo-title` 등) 및 텍스트 매칭 지점 `Title:`→`Locale:`로 조정, 전면 그린
-
-## 의사결정 기록(ADR)
-- [YYYY-MM-DD] Next.js(App Router) 채택: 생태계/배포/서버리스/SEO 편의성.
-- [YYYY-MM-DD] Sheets 기본 방안: Apps Script 웹앱 템플릿(사용자 편의/트래픽 분산).
-- [YYYY-MM-DD] 로컬 이미지 업로드 허용: 서버 저장 없이 ZIP에 `assets/`로 패키징(브라우저 JSZip 우선).
