## 1. 디자인 토큰 (하드코딩 제거)

모든 수치/색상은 CSS 변수 + TS 상수로 관리. 컴포넌트에 직접 px, #색상 금지.

## 2. 반응형 레이아웃 시스템

### 2.1 Breakpoint 전략

```
┌─────────────────────────────────────────────────────────┐
│  < 576px    Mobile       사이드바 숨김, 햄버거 메뉴     │
│  576~767px  Mobile+      사이드바 오버레이              │
│  768~991px  Tablet       사이드바 접힘 (아이콘만)       │
│  992~1199px Desktop      사이드바 펼침                  │
│  ≥ 1200px   Wide         사이드바 펼침 + 여유 공간      │

### 3.3 BaseFormDialog.vue

모든 생성/수정 다이얼로그의 공통 셸.

```vue

## 4. 반응형 폼 그리드

### 4.1 FormGrid 유틸리티 클래스

```scss
// src/assets/styles/_form-grid.scss
@use 'variables' as *;

// 폼 필드 컨테이너 — CSS Grid 기반
.form-grid {
  display: grid;
  gap: $space-md;
  grid-template-columns: repeat(12, 1fr);

  // 기본: 1열
  @media (max-width: $bp-mobile) {
    grid-template-columns: 1fr;
  }
}

// 컬럼 span 클래스
.col-1  { grid-column: span 1; }
.col-2  { grid-column: span 2; }
.col-3  { grid-column: span 3; }
.col-4  { grid-column: span 4; }
.col-6  { grid-column: span 6; }
.col-8  { grid-column: span 8; }
.col-12 { grid-column: span 12; }

// 모바일에서는 전부 full-width
@media (max-width: $bp-mobile) {
  [class^="col-"] {
    grid-column: span 1 !important;
  }
}

// 폼 필드 단위
.form-field {
  display: flex;
  flex-direction: column;
  gap: $space-xs;

  &__label {
    font-size: $font-size-sm;
    font-weight: 600;
    color: $color-text;

    &--required::after {
      content: ' *';
      color: $color-danger;
    }
  }

  &__error {
    font-size: $font-size-xs;
    color: $color-danger;
  }

  &__hint {
    font-size: $font-size-xs;
    color: $color-text-muted;
  }
}
```

### 4.2 사용 예시: UserFormDialog

```vue
<template>
  <BaseFormDialog
    v-model:visible="visible"
    :title="isEdit ? '사용자 수정' : '사용자 등록'"
    width="720px"
    :loading="saving"
    @submit="onSubmit"
  >
    <div class="form-grid">
      <!-- 이름 (6열) -->
      <div class="form-field col-6">
        <label class="form-field__label form-field__label--required">이름</label>
        <InputText v-model="form.fullName" />
        <small v-if="errors.fullName" class="form-field__error">{{ errors.fullName }}</small>
      </div>

      <!-- 이메일 (6열) -->
      <div class="form-field col-6">
        <label class="form-field__label form-field__label--required">이메일</label>
        <InputText v-model="form.email" type="email" />
      </div>

      <!-- 사번 (4열) -->
      <div class="form-field col-4">
        <label class="form-field__label">사번</label>
        <InputText v-model="form.employeeId" />
      </div>

      <!-- 부서 (4열) -->
      <div class="form-field col-4">
        <label class="form-field__label">부서</label>
        <Select v-model="form.department" :options="departments" optionLabel="name" />
      </div>

      <!-- Discipline (4열) -->
      <div class="form-field col-4">
        <label class="form-field__label">Discipline</label>
        <Select v-model="form.discipline" :options="disciplines" />
      </div>

      <!-- 역할 (12열 = full) -->
      <div class="form-field col-12">
        <label class="form-field__label">역할</label>
        <MultiSelect v-model="form.roles" :options="roleOptions" optionLabel="name" display="chip" />
      </div>
    </div>
  </BaseFormDialog>
</template>
```

반응형 동작:
- **Desktop (≥992px)**: 12열 그리드 → 이름(6) + 이메일(6) 한 줄, 사번(4) + 부서(4) + Discipline(4) 한 줄
- **Mobile (<576px)**: 모두 1열로 스택

## 5. 반응형 DataTable 전략

```vue
<!-- 표준 DataTable 반응형 패턴 -->
<DataTable
  :value="data"
  responsiveLayout="scroll"
  size="small"
  :breakpoint="BREAKPOINTS.tablet + 'px'"
>
  <!-- 항상 보이는 핵심 열 -->
  <Column field="name" header="이름" sortable />
  <Column field="status" header="상태" sortable style="width: 100px" />

  <!-- 태블릿 이상에서만 보이는 열 -->
  <Column
    field="department"
    header="부서"
    sortable
    :class="{ 'hidden-mobile': true }"
    headerClass="hidden-mobile"
  />

  <!-- 액션 열 (항상 보임, 고정 너비) -->
  <Column header="관리" style="width: 120px" frozen alignFrozen="right">
    <template #body="{ data }">
      <Button icon="pi pi-pencil" text rounded size="small" />
      <Button icon="pi pi-trash" text rounded size="small" severity="danger" />
    </template>
  </Column>
</DataTable>
```

```scss
// DataTable 반응형 헬퍼
@media (max-width: $bp-tablet) {
  .hidden-mobile {
    display: none !important;
  }
}
```

## 6. 대시보드 카드 그리드

```vue
<!-- 대시보드 반응형 카드 레이아웃 -->
<template>
  <div class="dashboard-grid">
    <StatCard v-for="stat in stats" :key="stat.label" v-bind="stat" />
  </div>
  <div class="dashboard-grid dashboard-grid--2col">
    <Card><TimesheetChart /></Card>
    <Card><PendingApprovalCard /></Card>
  </div>
</template>

<style lang="scss" scoped>
@use '@/assets/styles/variables' as *;

.dashboard-grid {
  display: grid;
  gap: $space-md;

  // 기본: 4열 (StatCard)
  grid-template-columns: repeat(4, 1fr);

  @media (max-width: $bp-wide) {
    grid-template-columns: repeat(2, 1fr);
  }
  @media (max-width: $bp-mobile) {
    grid-template-columns: 1fr;
  }

  // 2열 변형 (차트)
  &--2col {
    grid-template-columns: repeat(2, 1fr);

    @media (max-width: $bp-tablet) {
      grid-template-columns: 1fr;
    }
  }
}
</style>
```

## 7. main.scss 통합

```scss
// src/assets/styles/main.scss

// 1. 변수 (최상위)
@use 'variables';

// 2. 폼 그리드 유틸리티
@use 'form-grid';

// 3. PrimeVue 테마 오버라이드
@use 'overrides';

// 4. 글로벌 리셋/베이스
*,
*::before,
*::after {
  box-sizing: border-box;
}

html {
  font-size: 16px;
  -webkit-font-smoothing: antialiased;
}

body {
  margin: 0;
  font-family: var(--p-font-family);
  color: var(--p-text-color);
  background: var(--p-surface-ground);
}

// 5. 유틸리티 클래스 (최소한)
.text-center { text-align: center; }
.text-right  { text-align: right; }
.text-muted  { color: var(--p-text-muted-color); }
.text-sm     { font-size: variables.$font-size-sm; }
.text-xs     { font-size: variables.$font-size-xs; }
.mt-0 { margin-top: 0; }
.mb-0 { margin-bottom: 0; }

// 6. 카드 표준 (페이지 내 섹션)
.card {
  background: var(--p-surface-0);
  border: 1px solid var(--p-surface-200);
  border-radius: variables.$radius-md;
  padding: variables.$space-lg;

  @media (max-width: variables.$bp-mobile) {
    padding: variables.$space-md;
    border-radius: variables.$radius-sm;
  }
}
```

## 8. 표준 페이지 작성 템플릿

모든 목록 페이지는 아래 구조를 따릅니다:

```vue
<!-- modules/{module}/views/{Module}ListView.vue -->
<script setup lang="ts">
import { onMounted, ref } from 'vue';
import { useToast } from 'primevue/usetoast';

import { {MODULE}_STATUS } from '@/core/constants/app.constants';
import type { {Module} } from '../{module}.types';

const store = use{Module}Store();
const toast = useToast();
const confirm = useConfirm();

const showDialog = ref(false);
const selected = ref<{Module} | null>(null);

onMounted(() => store.fetchAll());

function openCreate() {
  selected.value = null;
  showDialog.value = true;
}

function openEdit(item: {Module}) {
  selected.value = { ...item };
  showDialog.value = true;
}

function confirmDelete(item: {Module}) {
  confirm.require({
    message: `"${item.name}" 을(를) 삭제하시겠습니까?`,
    header: '삭제 확인',
    icon: 'pi pi-exclamation-triangle',
    acceptClass: 'p-button-danger',
    acceptLabel: '삭제',
    rejectLabel: '취소',
    accept: async () => {
      await store.delete(item.id);
      toast.add({ severity: 'success', summary: '삭제 완료', life: 3000 });
    },
  });
}

async function onSaved() {
  showDialog.value = false;
  await store.fetchAll();
  toast.add({ severity: 'success', summary: '저장 완료', life: 3000 });
}
</script>

<template>
  <div>
    <BasePageHeader title="{모듈명} 관리" subtitle="설명 텍스트">
      <template #actions>
        <Button label="등록" icon="pi pi-plus" @click="openCreate" />
      </template>
    </BasePageHeader>

    <div class="card">
      <BaseCrudTable
        :value="store.items"
        :loading="store.loading"
        :globalFilterFields="['name', 'code']"
      >
        <Column field="name" header="이름" sortable />
        <Column field="status" header="상태" sortable style="width: 120px">
          <template #body="{ data }">
            <Tag
              :value="{MODULE}_STATUS[data.status]?.label"
              :severity="{MODULE}_STATUS[data.status]?.severity"
            />
          </template>
        </Column>
        <Column header="관리" style="width: 100px">
          <template #body="{ data }">
            <Button icon="pi pi-pencil" text rounded size="small" @click="openEdit(data)" />

          </template>
        </Column>
      </BaseCrudTable>
    </div>

    <{Module}FormDialog
      v-model:visible="showDialog"
      :item="selected"
      @saved="onSaved"
    />
  </div>
</template>
```
