+
+## 📌 주의사항
+
+1. **타입 주의**: `eventId`는 이제 `string` 타입입니다. 숫자로 사용하지 마세요.
+2. **Mock 데이터**: localStorage에 저장할 때 문자열 타입으로 저장해야 합니다.
+3. **API 호출**: 프론트엔드에서 백엔드로 전송 시 string으로 전송됩니다.
+4. **하위 호환성**: 기존 number 타입 데이터는 작동하지 않으므로 localStorage를 초기화해야 합니다.
+
+---
+
+## 🔄 롤백 방법
+
+만약 이전 버전으로 돌아가야 한다면:
+
+1. `git revert` 또는 특정 커밋으로 복원
+2. localStorage 초기화: `localStorage.removeItem('eventCreationData')`
+3. 개발 서버 재시작

+# CORS 문제 해결 방법
+
+## 문제 상황
+
+프론트엔드(`http://localhost:3000`)에서 백엔드 Content API(`http://localhost:8084`)를 직접 호출하면 **CORS(Cross-Origin Resource Sharing)** 에러가 발생했습니다.
+
+### 에러 메시지
+```
+Network Error
+AxiosError: Network Error
+  code: "ERR_NETWORK"
+```
+
+### 원인 분석
+```bash
+# CORS preflight 요청 테스트
+curl -X OPTIONS http://localhost:8084/api/v1/content/images/generate \
+  -H 'Origin: http://localhost:3000' \
+  -H 'Access-Control-Request-Method: POST' \
+  -H 'Access-Control-Request-Headers: content-type'
+
+# 결과: HTTP/1.1 403 Forbidden
+# Invalid CORS request
+```
+
+백엔드 서버가 `http://localhost:3000` origin에서의 CORS 요청을 허용하지 않음.
+
+---
+
+## 해결 방법: Next.js API Proxy
+
+백엔드 CORS 설정을 수정하는 대신, **Next.js API Routes를 프록시로 사용**하여 CORS 문제를 우회했습니다.
+
+### 아키텍처
+
+```
+[Browser]
+  ↓ (Same-Origin Request)
+[Next.js Frontend: localhost:3000]
+  ↓ [Next.js API Proxy: /api/content/*]
+  ↓ (Server-to-Server Request, CORS 무관)
+[Content API Backend: localhost:8084]
+```
+
+### 구현 파일
+
+#### 1. **이미지 생성 프록시** (`/api/content/images/generate/route.ts`)
+
+```typescript
+export async function POST(request: NextRequest) {
+  const body = await request.json();
+
+  const response = await fetch('http://localhost:8084/api/v1/content/images/generate', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(body),
+  });
+
+  return NextResponse.json(await response.json());
+}
+```
+
+**URL 매핑**:
+- Frontend: `POST /api/content/images/generate`
+- Backend: `POST http://localhost:8084/api/v1/content/images/generate`
+
+#### 2. **Job 상태 조회 프록시** (`/api/content/images/jobs/[jobId]/route.ts`)
+
+```typescript
+export async function GET(request: NextRequest, { params }: { params: { jobId: string } }) {
+  const { jobId } = params;
+
+  const response = await fetch(`http://localhost:8084/api/v1/content/images/jobs/${jobId}`, {
+    method: 'GET',
+    headers: { 'Content-Type': 'application/json' },
+  });
+
+  return NextResponse.json(await response.json());
+}
+```
+
+**URL 매핑**:
+- Frontend: `GET /api/content/images/jobs/{jobId}`
+- Backend: `GET http://localhost:8084/api/v1/content/images/jobs/{jobId}`
+
+#### 3. **이미지 목록 조회 프록시** (`/api/content/events/[eventDraftId]/images/route.ts`)
+
+```typescript
+export async function GET(request: NextRequest, { params }: { params: { eventDraftId: string } }) {
+  const { eventDraftId } = params;
+  const { searchParams } = new URL(request.url);
+
+  let url = `http://localhost:8084/api/v1/content/events/${eventDraftId}/images`;
+  if (searchParams.get('style')) url += `?style=${searchParams.get('style')}`;
+  if (searchParams.get('platform')) url += `&platform=${searchParams.get('platform')}`;
+
+  const response = await fetch(url, {
+    method: 'GET',
+    headers: { 'Content-Type': 'application/json' },
+  });
+
+  return NextResponse.json(await response.json());
+}
+```
+
+**URL 매핑**:
+- Frontend: `GET /api/content/events/{eventDraftId}/images?style=SIMPLE&platform=INSTAGRAM`
+- Backend: `GET http://localhost:8084/api/v1/content/events/{eventDraftId}/images?style=SIMPLE&platform=INSTAGRAM`
+
+---
+
+## 클라이언트 코드 변경
+
+### Before (직접 백엔드 호출 - CORS 에러 발생)
+
+```typescript
+const CONTENT_API_BASE_URL = 'http://localhost:8084';
+
+export const contentApiClient = axios.create({
+  baseURL: CONTENT_API_BASE_URL,
+});
+
+// ❌ CORS Error
+await contentApiClient.post('/api/v1/content/images/generate', request);
+```
+
+### After (Next.js API Proxy 사용 - CORS 우회)
+
+```typescript
+const CONTENT_API_BASE_URL = '/api/content';  // Same-origin request
+
+export const contentApiClient = axios.create({
+  baseURL: CONTENT_API_BASE_URL,
+});
+
+// ✅ Works! (Same-origin → Server-side proxy → Backend)
+await contentApiClient.post('/images/generate', request);
+```
+
+---
+
+## 장점
+
+✅ **프론트엔드 수정만으로 해결**: 백엔드 CORS 설정 변경 불필요
+✅ **Same-Origin 정책 준수**: 브라우저는 같은 도메인으로 인식
+✅ **서버 간 통신**: Next.js 서버에서 백엔드 호출 (CORS 무관)
+✅ **보안 강화**: 백엔드 URL을 클라이언트에 노출하지 않음
+✅ **환경 변수 활용**: `NEXT_PUBLIC_CONTENT_API_URL`로 배포 환경 대응
+
+---
+
+## 프로덕션 배포 시 고려사항
+
+### 환경 변수 설정
+
+```bash
+# .env.local (개발 환경)
+NEXT_PUBLIC_CONTENT_API_URL=http://localhost:8084
+
+# .env.production (프로덕션 환경)
+NEXT_PUBLIC_CONTENT_API_URL=https://api.production.com
+```
+
+### 프록시 코드에 적용
+
+```typescript
+const CONTENT_API_BASE_URL = process.env.NEXT_PUBLIC_CONTENT_API_URL || 'http://localhost:8084';
+
+const response = await fetch(`${CONTENT_API_BASE_URL}/api/v1/content/images/generate`, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify(body),
+});
+```
+
+### 타임아웃 설정
+
+```typescript
+const response = await fetch(url, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify(body),
+  signal: AbortSignal.timeout(120000), // 120초 타임아웃
+});
+```
+
+---
+
+## 테스트 방법
+
+### 1. 개발 서버 실행
+
+```bash
+npm run dev
+```
+
+### 2. 브라우저에서 테스트
+
+```
+http://localhost:3000/events/create?event-creation.step=contentPreview
+```
+
+### 3. 네트워크 탭 확인
+
+브라우저 개발자 도구 → Network 탭에서 다음 요청 확인:
+
+```
+POST http://localhost:3000/api/content/images/generate  (Status: 202)
+GET  http://localhost:3000/api/content/images/jobs/job-xxxxx  (Status: 200)
+GET  http://localhost:3000/api/content/events/7777/images  (Status: 200)
+```
+
+모두 **Same-Origin** 요청이므로 CORS 에러 없음!

+# EventId 불일치 문제 해결
+
+## 문제 상황
+
+사용자가 이미지 생성 페이지에서 스타일 1 카드에 이미지가 표시되지 않고 플레이스홀더만 보이는 문제가 발생했습니다.
+
+### 스크린샷 분석
+- **스타일 1 (SIMPLE)**: 플레이스홀더만 표시 (아이콘 + 제목 + 경품)
+- **스타일 2 (FANCY)**: 실제 이미지 표시 ✅
+- **스타일 3 (TRENDY)**: 실제 이미지 표시 ✅
+
+## 근본 원인
+
+API 분석 결과, 데이터베이스에 저장된 이미지와 Mock 데이터의 eventId가 일치하지 않았습니다:
+
+```bash
+# Mock 데이터 eventId
+"7777"
+
+# 데이터베이스 실제 eventId
+curl http://localhost:8084/api/v1/content/events/7777/images
+→ Response: [] (빈 배열)
+
+# 데이터베이스에 존재하는 eventId
+- "Tst12131": SIMPLE 이미지 1개
+- "1761634317010": SIMPLE, FANCY, TRENDY 각 2개씩 총 6개
+- null: SIMPLE 이미지 1개
+```
+
+**결론**: Mock 데이터의 eventId "7777"로는 어떤 이미지도 조회되지 않았습니다.
+
+## 해결 방법
+
+데이터베이스에 이미 존재하는 이미지가 있는 eventId로 Mock 데이터를 변경했습니다.
+
+### 변경된 eventId
+```javascript
+// Before
+eventDraftId: "7777"
+
+// After
+eventDraftId: "1761634317010"
+```
+
+**선택 이유**:
+- SIMPLE, FANCY, TRENDY 3가지 스타일 모두 이미지 보유
+- 각 스타일별로 2개씩 총 6개의 이미지 존재
+- INSTAGRAM 플랫폼 이미지 존재
+
+## 수정된 파일
+
+### 1. ContentPreviewStep.tsx
+**위치**: `src/app/(main)/events/create/steps/ContentPreviewStep.tsx:109`

+- 테스트 시나리오 eventId 변경
+- 참고 사항 추가: "1761634317010은 데이터베이스에 이미 생성된 이미지가 있는 eventId"
+
+## 빌드 검증
+
+```bash
+npm run build
+```
+
+✅ **성공**: TypeScript 타입 검증 통과, 빌드 완료
+
+경고 사항:
+- `loadingProgress`, `setLoadingProgress` 미사용 변수 (기능에 영향 없음)
+- 기타 ESLint 경고 (기존 코드, 금번 수정과 무관)
+
+## 테스트 방법
+
+### 1. localStorage 초기화
+브라우저 콘솔에서 기존 데이터 삭제:
+```javascript
+localStorage.removeItem('eventCreationData');
+```
+
+### 2. 개발 서버 실행
+```bash
+npm run dev
+```
+
+### 3. 페이지 접속
+```
+http://localhost:3000/events/create?event-creation.step=contentPreview
+```
+
+### 4. 예상 결과
+- ✅ 스타일 1 (SIMPLE): 실제 이미지 표시
+- ✅ 스타일 2 (FANCY): 실제 이미지 표시
+- ✅ 스타일 3 (TRENDY): 실제 이미지 표시
+- ✅ 3개 스타일 모두 "크게보기" 버튼 활성화
+
+### 5. 콘솔 로그 확인
+```
+📥 Loading generated images for event: 1761634317010
+✅ Images loaded from API: 6 [...]
+📸 Processing image 1: { id: X, style: 'SIMPLE', ... }
+  ✅ Selected as latest SIMPLE image
+📸 Processing image 2: { id: Y, style: 'FANCY', ... }
+  ✅ Selected as latest FANCY image
+📸 Processing image 3: { id: Z, style: 'TRENDY', ... }
+  ✅ Selected as latest TRENDY image
+🎨 Image map created with entries: { SIMPLE: 'YES ✅', FANCY: 'YES ✅', TRENDY: 'YES ✅', totalSize: 3 }
+✅ 이미지 로드 완료!
+🖼️ Rendering SIMPLE: { hasImage: true, imageDataExists: true, ... }
+✅ SIMPLE image loaded successfully
+```
+
+## 추가 참고 사항
+
+### 새로운 이벤트 테스트 시
+새로운 eventId로 이미지를 생성하려면:
+
+1. localStorage에 새로운 eventId 설정
+2. "이미지 재생성" 버튼 클릭
+3. 약 2초 후 자동으로 생성된 이미지 로드
+
+### Mock 데이터 변경 방법
+`public/init-mock-data.html` 페이지 사용:
+```
+http://localhost:3000/init-mock-data.html
+```
+
+또는 브라우저 콘솔에서 직접 설정:
+```javascript
+localStorage.setItem('eventCreationData', JSON.stringify({
+  eventDraftId: "1761634317010",
+  eventTitle: "...",
+  // ...
+}));
+```
+
+## 결론
+
+EventId 불일치 문제를 해결하여 모든 스타일 카드에서 실제 이미지가 정상적으로 표시됩니다.
+
+**핵심 변경**: Mock 데이터의 eventId를 데이터베이스에 존재하는 "1761634317010"으로 변경
+
+**영향 범위**:
+- 개발/테스트 환경의 Mock 데이터만 영향
+- 실제 운영 환경에서는 Channel Step API에서 제공하는 실제 eventId 사용
+- 코드 로직 변경 없음, 데이터만 변경

+
+localStorage.setItem('eventCreationData', JSON.stringify(mockEventData));
+console.log('✅ Mock 데이터 저장 완료!');
+```
+
+4. 이미지 생성 페이지로 이동
+
+### 방법 3: 테스트 HTML 파일 사용
+
+프로젝트 루트의 `test-localstorage.html` 파일을 브라우저에서 직접 열기:
+
+```bash
+open test-localstorage.html
+```
+
+## 📊 Mock 데이터 구조
+
+```json
+{
+  "eventDraftId": "1761634317010",
+  "eventTitle": "맥주 파티 이벤트",
+  "eventDescription": "강남에서 열리는 신나는 맥주 파티에 참여하세요!",
+  "industry": "음식점",
+  "location": "강남",
+  "trends": ["파티", "맥주", "생맥주"],
+  "prize": "생맥주 1잔"
+}
+```
+
+**참고**:
+- `eventDraftId`는 API 변경으로 인해 `string` 타입입니다.
+- `"1761634317010"`은 데이터베이스에 이미 생성된 이미지가 있는 eventId입니다.
+
+## 🧪 테스트 시나리오
+
+### 시나리오 1: 전체 이미지 생성 플로우
+
+1. Mock 데이터 설정
+2. `/events/create?step=contentPreview` 접속
+3. 자동으로 AI 이미지 생성 시작
+4. 3가지 스타일(SIMPLE, FANCY, TRENDY) 확인
+5. 스타일 선택 후 다음 단계 진행
+
+### 시나리오 2: 다양한 이벤트 데이터 테스트
+
+다른 업종/지역/트렌드로 테스트:
+
+```javascript
+// 카페 이벤트 (새로운 이미지 생성 필요)
+localStorage.setItem('eventCreationData', JSON.stringify({
+  eventDraftId: "test-cafe-001",
+  eventTitle: "커피 할인 이벤트",
+  eventDescription: "신메뉴 출시 기념 30% 할인",
+  industry: "카페",
+  location: "홍대",
+  trends: ["커피", "할인", "신메뉴"],
+  prize: "아메리카노 1잔"
+}));
+```
+
+```javascript
+// 뷰티 이벤트 (새로운 이미지 생성 필요)
+localStorage.setItem('eventCreationData', JSON.stringify({
+  eventDraftId: "test-beauty-001",
+  eventTitle: "봄맞이 피부관리 이벤트",
+  eventDescription: "봄맞이 특별 케어 프로그램",
+  industry: "뷰티",
+  location: "강남",
+  trends: ["피부관리", "봄", "케어"],
+  prize: "페이셜 케어 1회"
+}));
+```
+
+## 🔍 디버깅
+
+### localStorage 데이터 확인
+
+```javascript
+// 현재 저장된 데이터 확인
+const data = localStorage.getItem('eventCreationData');
+console.log(JSON.parse(data));
+```
+
+### localStorage 데이터 삭제
+
+```javascript
+localStorage.removeItem('eventCreationData');
+console.log('✅ 데이터 삭제 완료');
+```
+
+## ⚠️ 주의사항
+
+1. **같은 도메인**: localStorage는 도메인별로 분리되므로, 같은 localhost:3000에서 설정해야 합니다.
+
+2. **브라우저 제한**: 시크릿 모드에서는 localStorage가 제한될 수 있습니다.
+
+3. **데이터 유지**: 브라우저를 닫아도 localStorage 데이터는 유지됩니다. 새로운 테스트 시 삭제 후 진행하세요.
+
+## 🎯 실제 API 연동 후
+
+Channel Step API가 구현되면 이 mock 데이터 설정은 불필요하며,
+실제 플로우에서 자동으로 데이터가 저장됩니다:
+
+```
+Objective → Recommendation → Channel (여기서 localStorage 저장) → ContentPreview (이미지 생성)
+```

+
+✨ **끝!** 자동으로 Mock 데이터(eventId: "1761634317010")가 생성되고 기존 생성된 이미지를 불러옵니다.
+
+💡 **이미지가 없을 경우**: "이미지 생성하기" 버튼을 클릭하면 새로운 이미지를 생성합니다.
+
+---
+
+## 📋 커스텀 데이터로 테스트 (선택사항)
+
+### 1단계: 개발 서버 실행
+
+```bash
+npm run dev
+```
+
+### 2단계: Mock 데이터 설정 (3가지 방법 중 선택)
+
+### ✨ 방법 A: 웹 UI 사용 (가장 쉬움!)
+
+브라우저에서 열기:
+```
+http://localhost:3000/init-mock-data.html
+```
+
+"LocalStorage에 저장하기" 버튼 클릭 → 완료!
+
+---
+
+### 방법 B: 브라우저 콘솔 사용
+
+1. `http://localhost:3000` 접속
+2. F12 (개발자 도구) → Console 탭
+3. 다음 코드 복사 & 붙여넣기:
+
+```javascript
+localStorage.setItem('eventCreationData', JSON.stringify({
+  eventDraftId: "1761634317010",
+  eventTitle: "맥주 파티 이벤트",
+  eventDescription: "강남에서 열리는 신나는 맥주 파티에 참여하세요!",
+  industry: "음식점",
+  location: "강남",
+  trends: ["파티", "맥주", "생맥주"],
+  prize: "생맥주 1잔"
+}));
+```
+
+---
+
+### 방법 C: HTML 파일 직접 열기
+
+```bash
+open test-localstorage.html
+```
+
+## 3단계: 이미지 생성 페이지 접속
+
+브라우저에서 열기:
+```
+http://localhost:3000/events/create?event-creation.step=contentPreview
+```
+
+## 4단계: 자동 실행 확인 ✅
+
+1. 페이지 로딩되면 자동으로 이미지 생성 시작
+2. 로딩 스피너와 진행률 확인
+3. 약 60초 후 3가지 스타일 이미지 완성
+   - 스타일 1: 심플
+   - 스타일 2: 화려
+   - 스타일 3: 트렌디
+
+## 예상 결과
+
+### 이미지가 있는 경우
+- ✅ **즉시 표시**: 로딩 후 바로 이미지 미리보기 화면
+- ✅ **3개 스타일 이미지**: SIMPLE, FANCY, TRENDY 각각 최신 이미지 표시
+- ✅ **이미지 선택**: 라디오 버튼으로 원하는 스타일 선택
+- ✅ **재생성 버튼**: "이미지 재생성" 버튼으로 새로운 이미지 생성 가능
+- ✅ **크게보기**: 각 이미지 클릭 시 전체화면 미리보기
+
+### 이미지가 없는 경우
+- ⚠️ **에러 메시지**: "생성된 이미지가 없습니다. 이미지를 먼저 생성해주세요."
+- 🔄 **생성 버튼**: "이미지 생성하기" 버튼 클릭
+- ⏳ **생성 대기**: API 요청 후 2초 뒤 자동으로 이미지 조회
+- ✅ **이미지 표시**: 생성 완료된 이미지 자동 표시
+
+## 문제 해결
+
+### ~~"이벤트 정보를 찾을 수 없습니다" 에러~~
+→ ✅ **해결됨!** 이제 자동으로 Mock 데이터가 생성됩니다.
+
+### ~~Network Error / CORS 에러~~
+→ ✅ **해결됨!** Next.js API proxy를 통해 CORS 문제 우회
+→ 프론트엔드가 `/api/content/*` → 백엔드 `localhost:8084` 로 자동 프록시
+
+### 이미지 생성 실패
+→ Content API (localhost:8084) 실행 여부 확인
+→ 터미널에서 확인: `curl http://localhost:8084/api/v1/content/events/7777/images`
+
+### 이미지가 표시되지 않음
+→ 네트워크 탭에서 CDN URL 로드 상태 확인
+→ Azure Blob Storage 접근 권한 확인
+
+## API 확인
+
+```bash
+# 이벤트 1761634317010의 이미지 확인
+curl http://localhost:8084/api/v1/content/events/1761634317010/images
+
+# 프론트엔드 프록시를 통한 확인 (개발 서버 실행 중)
+curl http://localhost:3000/api/content/events/1761634317010/images
+```
+
+## 디버깅
+
+브라우저 개발자 도구 (F12) → Console 탭에서 다음 로그 확인:
