+# 관리자 페이지 표준 스타일 가이드
+
+이 가이드는 관리자 페이지의 일관된 UI/UX를 위한 표준 스타일 규칙입니다.
+모든 관리자 페이지는 이 가이드를 따라야 합니다.
+
+## 1. 페이지 레이아웃 구조
+
+### 기본 페이지 템플릿
+
+```tsx
+export default function AdminPage() {
+  return (
+    <div className="flex min-h-screen flex-col bg-background">
+      <div className="space-y-6 p-6">
+        {/* 페이지 헤더 */}
+        <div className="space-y-2 border-b pb-4">
+          <h1 className="text-3xl font-bold tracking-tight">페이지 제목</h1>
+          <p className="text-sm text-muted-foreground">페이지 설명</p>
+        </div>
+
+        {/* 메인 컨텐츠 */}
+        <MainComponent />
+      </div>
+
+      {/* Scroll to Top 버튼 (모바일/태블릿 전용) */}
+      <ScrollToTop />
+    </div>
+  );
+}
+```
+
+**필수 적용 사항:**
+
+- 최상위: `flex min-h-screen flex-col bg-background`
+- 컨텐츠 영역: `space-y-6 p-6` (24px 좌우 여백, 24px 간격)
+- 헤더 구분선: `border-b pb-4` (테두리 박스 사용 금지)
+- Scroll to Top: 모든 관리자 페이지에 포함
+
+## 2. Color System (색상 시스템)
+
+### CSS Variables 사용 (하드코딩 금지)
+
+```tsx
+// ❌ 잘못된 예시
+<div className="bg-gray-50 text-gray-900 border-gray-200">
+
+// ✅ 올바른 예시
+<div className="bg-background text-foreground border-border">
+<div className="bg-card text-card-foreground">
+<div className="bg-muted text-muted-foreground">
+```
+
+**표준 색상 토큰:**
+
+- `bg-background` / `text-foreground`: 기본 배경/텍스트
+- `bg-card` / `text-card-foreground`: 카드 배경/텍스트
+- `bg-muted` / `text-muted-foreground`: 보조 배경/텍스트
+- `bg-primary` / `text-primary`: 메인 액션
+- `bg-destructive` / `text-destructive`: 삭제/에러
+- `border-border`: 테두리
+- `ring-ring`: 포커스 링
+
+## 3. Typography (타이포그래피)
+
+### 표준 텍스트 크기와 가중치
+
+```tsx
+// 페이지 제목
+<h1 className="text-3xl font-bold tracking-tight">
+
+// 섹션 제목
+<h2 className="text-xl font-semibold">
+<h3 className="text-lg font-semibold">
+<h4 className="text-sm font-semibold">
+
+// 본문 텍스트
+<p className="text-sm">
+
+// 보조 텍스트
+<p className="text-sm text-muted-foreground">
+<p className="text-xs text-muted-foreground">
+
+// 라벨
+<label className="text-sm font-medium">
+```
+
+## 4. Spacing System (간격)
+
+### 일관된 간격 (4px 기준)
+
+```tsx
+// 페이지 레벨 간격
+<div className="space-y-6">        // 24px
+
+// 섹션 레벨 간격
+<div className="space-y-4">        // 16px
+
+// 필드 레벨 간격
+<div className="space-y-2">        // 8px
+
+// 패딩
+<div className="p-6">              // 24px (카드)
+<div className="p-4">              // 16px (내부 섹션)
+
+// 갭
+<div className="gap-4">            // 16px (flex/grid)
+<div className="gap-2">            // 8px (버튼 그룹)
+```
+
+## 5. 검색 툴바 (Toolbar)
+
+### 패턴 A: 통합 검색 영역 (권장)
+
+```tsx
+<div className="space-y-4">
+  {/* 검색 및 액션 영역 */}
+  <div className="flex flex-col gap-4 lg:flex-row lg:items-center lg:justify-between">
+    {/* 검색 영역 */}
+    <div className="flex flex-col gap-4 sm:flex-row sm:items-center">
+      {/* 통합 검색 */}
+      <div className="w-full sm:w-[400px]">
+        <div className="relative">

+          <Input placeholder="통합 검색..." className="h-10 pl-10 text-sm" />
+        </div>
+      </div>
+
+      {/* 고급 검색 토글 */}
+      <Button variant="outline" className="h-10 gap-2 text-sm font-medium">
+        고급 검색
+      </Button>
+    </div>
+
+    {/* 액션 버튼 영역 */}
+    <div className="flex items-center gap-4">
+      <div className="text-sm text-muted-foreground">
+        총{" "}
+        <span className="font-semibold text-foreground">
+          {count.toLocaleString()}
+        </span>{" "}
+        건
+      </div>
+      <Button className="h-10 gap-2 text-sm font-medium">

+        등록
+      </Button>
+    </div>
+  </div>
+
+  {/* 고급 검색 옵션 */}
+  {showAdvanced && (
+    <div className="space-y-4">
+      <div className="space-y-1">
+        <h4 className="text-sm font-semibold">고급 검색 옵션</h4>
+        <p className="text-xs text-muted-foreground">설명</p>
+      </div>
+      <div className="grid grid-cols-1 gap-4 sm:grid-cols-2 lg:grid-cols-4">
+        <Input placeholder="필드 검색" className="h-10 text-sm" />
+      </div>
+    </div>
+  )}
+</div>
+```
+
+### 패턴 B: 제목 + 검색 + 버튼 한 줄 (공간 효율적)
+
+```tsx
+{
+  /* 상단 헤더: 제목 + 검색 + 버튼 */
+}
+<div className="relative flex flex-col gap-4 lg:flex-row lg:items-center lg:justify-between">
+  {/* 왼쪽: 제목 */}

+              className="flex cursor-pointer items-center px-2 py-1.5 text-sm hover:bg-accent hover:text-accent-foreground"
+              onClick={() => {
+                setValue(option.value);
+                setIsOpen(false);
+              }}
+            >
+              {option.label}
+            </div>
+          ))}
+        </div>
+      </div>
+    )}
+  </div>
+</div>;
+```
+
+**필수 적용 사항:**
+
+- ✅ z-index: `z-[100]` (다른 요소 위에 표시)
+- ✅ 그림자: `shadow-lg` (명확한 레이어 구분)
+- ✅ 최소 너비: `min-w-[200px]` (내용이 잘리지 않도록)
+- ✅ 최대 높이: `max-h-48` (스크롤 가능)
+- ✅ 애니메이션: 화살표 아이콘 회전 (`rotate-180`)
+- ✅ 부모 요소: `relative` 클래스 필요
+- ⚠️ 부모에 `overflow-hidden` 사용 시 드롭다운 잘림 주의
+
+**드롭다운이 잘릴 때 해결방법:**
+
+```tsx
+// 부모 요소의 overflow 제거
+<div className="w-[80%] pl-0">  // overflow-hidden 제거
+
+// 또는 상단 헤더에 relative 추가
+<div className="relative flex ...">  // 드롭다운 포지셔닝 기준점
+```
+
+## 15. Scroll to Top Button
+
+### 모바일/태블릿 전용 버튼
+
+```tsx
+import { ScrollToTop } from "@/components/common/ScrollToTop";
+
+// 페이지에 추가
+<ScrollToTop />;
+```
+
+**특징:**
+
+- 데스크톱에서 숨김 (`lg:hidden`)
+- 스크롤 200px 이상 시 나타남
+- 부드러운 페이드 인/아웃 애니메이션
+- 오른쪽 하단 고정 위치
+- 원형 디자인 (`rounded-full`)
+
+## 14. Accessibility (접근성)
+
+### 필수 적용 사항
+
+```tsx
+// Label과 Input 연결
+<label htmlFor="field-id" className="text-sm font-medium">
+  라벨
+</label>
+<Input id="field-id" />
+
+// 버튼에 aria-label
+<Button aria-label="설명">
+  <Icon />
+</Button>
+
+// Switch에 aria-label
+<Switch
+  checked={isActive}
+  onCheckedChange={handleChange}
+  aria-label="상태 토글"
+/>
+
+// 포커스 표시 (자동 적용)
+focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring
+```
+
+## 15. Class 순서 (일관성)
+
+### 표준 클래스 작성 순서
+
+1. Layout: `flex`, `grid`, `block`
+2. Position: `fixed`, `absolute`, `relative`

+8. Effects: `shadow-sm`, `opacity-50`
+9. States: `hover:`, `focus:`, `disabled:`
+10. Responsive: `sm:`, `md:`, `lg:`
+
+## 16. 금지 사항
+
+### ❌ 절대 사용하지 말 것
+
+1. 하드코딩된 색상 (`bg-gray-50`, `text-blue-500` 등)
+2. 인라인 스타일로 색상 지정 (`style={{ color: '#3b82f6' }}`)

+# 관리자 페이지 스타일 가이드 적용 예시
+
+## 개요
+
+사용자 관리 페이지를 예시로 shadcn/ui 스타일 가이드에 맞춰 재작성했습니다.
+이 예시를 기준으로 다른 관리자 페이지들도 일관된 스타일로 통일할 수 있습니다.
+
+## 적용된 주요 원칙
+
+### 1. Color System (색상 시스템)
+
+**CSS Variables 사용 (하드코딩된 색상 금지)**
+```tsx
+// ❌ 잘못된 예시
+<div className="bg-gray-50 text-gray-900">
+
+// ✅ 올바른 예시
+<div className="bg-background text-foreground">
+<div className="bg-card text-card-foreground">
+<div className="bg-muted text-muted-foreground">
+<div className="text-primary">
+<div className="text-destructive">
+```
+
+**적용 사례:**
+- 페이지 배경: `bg-background`
+- 카드 배경: `bg-card`
+- 보조 텍스트: `text-muted-foreground`
+- 주요 액션: `text-primary`, `border-primary`
+- 에러 메시지: `text-destructive`, `bg-destructive/10`
+
+### 2. Typography (타이포그래피)
+
+**일관된 폰트 크기와 가중치**
+```tsx
+// 페이지 제목
+<h1 className="text-3xl font-bold tracking-tight">사용자 관리</h1>
+
+// 섹션 제목
+<h4 className="text-sm font-semibold">고급 검색 옵션</h4>
+
+// 본문 텍스트
+<p className="text-sm text-muted-foreground">설명 텍스트</p>
+
+// 라벨
+<label className="text-sm font-medium">필드 라벨</label>
+
+// 보조 텍스트
+<p className="text-xs text-muted-foreground">도움말</p>
+```
+
+### 3. Spacing System (간격)
+
+**일관된 간격 사용 (4px 기준)**
+```tsx
+// 컴포넌트 간 간격
+<div className="space-y-6">          // 24px (페이지 레벨)
+<div className="space-y-4">          // 16px (섹션 레벨)
+<div className="space-y-2">          // 8px (필드 레벨)
+
+// 패딩
+<div className="p-6">                // 24px (카드)
+<div className="p-4">                // 16px (내부 섹션)
+
+// 갭
+<div className="gap-4">              // 16px (flex/grid)
+<div className="gap-2">              // 8px (버튼 그룹)
+```
+
+### 4. Border & Radius (테두리 및 둥근 모서리)
+
+**표준 radius 사용**
+```tsx
+// 카드/패널
+<div className="rounded-lg border bg-card">
+
+// 입력 필드
+<Input className="rounded-md">
+
+// 버튼
+<Button className="rounded-md">
+```
+
+### 5. Button Variants (버튼 스타일)
+
+**표준 variants 사용**
+```tsx
+// Primary 액션
+<Button variant="default" size="default" className="h-10 gap-2 text-sm font-medium">
+  <Plus className="h-4 w-4" />
+  사용자 등록
+</Button>
+
+// Secondary 액션
+<Button variant="outline" size="default" className="h-10 gap-2 text-sm font-medium">
+  고급 검색
+</Button>
+
+// Ghost 버튼 (아이콘 전용)
+<Button variant="ghost" size="icon" className="h-8 w-8">
+  <Key className="h-4 w-4" />
+</Button>
+```
+
+**크기 표준:**
+- `h-10`: 기본 버튼 (40px)
+- `h-9`: 작은 버튼 (36px)
+- `h-8`: 아이콘 버튼 (32px)
+
+### 6. Input States (입력 필드 상태)
+
+**표준 Input 스타일**
+```tsx
+// 기본
+<Input className="h-10 text-sm" />
+
+// 포커스 (자동 적용)
+// focus:ring-2 focus:ring-ring
+
+// 로딩/액티브
+<Input className="h-10 text-sm border-primary ring-2 ring-primary/20" />
+
+// 비활성화
+<Input disabled className="cursor-not-allowed bg-muted text-muted-foreground" />
+```
+
+### 7. Form Structure (폼 구조)
+
+**표준 필드 구조**
+```tsx
+<div className="space-y-2">
+  <label htmlFor="field-id" className="text-sm font-medium">
+    필드 라벨
+  </label>
+  <Input
+    id="field-id"
+    placeholder="힌트 텍스트"
+    className="h-10 text-sm"
+  />
+  <p className="text-xs text-muted-foreground">
+    도움말 텍스트
+  </p>
+</div>
+```
+
+### 8. Table Structure (테이블 구조)
+
+**표준 테이블 스타일**
+```tsx
+<div className="rounded-lg border bg-card shadow-sm">
+  <Table>
+    <TableHeader>
+      <TableRow className="border-b bg-muted/50 hover:bg-muted/50">
+        <TableHead className="h-12 text-sm font-semibold">
+          컬럼명
+        </TableHead>
+      </TableRow>
+    </TableHeader>
+    <TableBody>
+      <TableRow className="border-b transition-colors hover:bg-muted/50">
+        <TableCell className="h-16 text-sm">
+          데이터
+        </TableCell>
+      </TableRow>
+    </TableBody>
+  </Table>
+</div>
+```
+
+**높이 표준:**
+- 헤더: `h-12` (48px)
+- 데이터 행: `h-16` (64px)
+
+### 9. Loading States (로딩 상태)
+
+**Skeleton UI**
+```tsx
+<div className="h-4 animate-pulse rounded bg-muted"></div>
+```
+
+### 10. Empty States (빈 상태)
+
+**표준 Empty State**
+```tsx
+<TableCell colSpan={columns} className="h-32 text-center">
+  <div className="flex flex-col items-center justify-center gap-2 text-muted-foreground">
+    <p className="text-sm">등록된 데이터가 없습니다.</p>
+  </div>
+</TableCell>
+```
+
+### 11. Error States (에러 상태)
+
+**표준 에러 메시지**
+```tsx
+<div className="rounded-lg border border-destructive/50 bg-destructive/10 p-4">
+  <div className="flex items-center justify-between">
+    <p className="text-sm font-semibold text-destructive">오류가 발생했습니다</p>
+    <button
+      onClick={clearError}
+      className="text-destructive transition-colors hover:text-destructive/80"
+      aria-label="에러 메시지 닫기"
+    >
+      ✕
+    </button>
+  </div>
+  <p className="mt-1.5 text-sm text-destructive/80">{errorMessage}</p>
+</div>
+```
+
+### 12. Responsive Design (반응형)
+
+**모바일 우선 접근**
+```tsx
+// 레이아웃
+<div className="flex flex-col gap-4 sm:flex-row sm:items-center">
+
+// 그리드
+<div className="grid grid-cols-1 gap-4 sm:grid-cols-2 lg:grid-cols-4">
+
+// 텍스트
+<h1 className="text-2xl sm:text-3xl font-bold">
+
+// 간격
+<div className="p-4 sm:p-6">
+```
+
+### 13. Accessibility (접근성)
+
+**필수 적용 사항**
+```tsx
+// Label과 Input 연결
+<label htmlFor="user-id" className="text-sm font-medium">
+  사용자 ID
+</label>
+<Input id="user-id" />
+
+// 버튼에 aria-label
+<Button aria-label="에러 메시지 닫기">
+  ✕
+</Button>
+
+// Switch에 aria-label
+<Switch
+  checked={isActive}
+  onCheckedChange={handleChange}
+  aria-label="사용자 상태 토글"
+/>
+```
