+<!-- CODEGRAPH_START -->
+## CodeGraph
+
+In repositories indexed by CodeGraph (a `.codegraph/` directory exists at the repo root), reach for it BEFORE grep/find or reading files when you need to understand or locate code:
+
+- **MCP tool** (when available): `codegraph_explore` answers most code questions in one call — the relevant symbols' verbatim source plus the call paths between them, including dynamic-dispatch hops grep can't follow. Name a file or symbol in the query to read its current line-numbered source. If it's listed but deferred, load it by name via tool search.
+- **Shell** (always works): `codegraph explore "<symbol names or question>"` prints the same output.
+
+If there is no `.codegraph/` directory, skip CodeGraph entirely — indexing is the user's decision.

+## 2. 断点体系
+
+使用 antd v6 内置 `Grid.useBreakpoint()` hook，映射三类设备行为：
+
+| 端侧 | antd 断点 | 视口宽度 | 布局行为 |
+|------|-----------|---------|---------|
+| 手机 | `xs` | < 576px | Drawer 抽屉菜单，padding 12px |
+| 平板 | `sm`, `md` | 576-991px | 侧栏默认折叠，padding 16px |
+| 桌面 | `lg`, `xl`, `xxl` | ≥ 992px | 侧栏可折叠（默认展开），padding 24px |
+
+**选择理由：** 使用 antd 内置断点与 `Row/Col` 响应式 props 天然一致，避免维护两套断点逻辑。992px 与最初规划的 1024px 相差 32px，实际设备无感知。
+
+## 3. 核心决策
+
+### 3.1 MainLayout 响应式检测
+
+**当前：** `useState(window.innerWidth < 768)` + `resize` 事件 → `isMobile` 布尔值
+
+**目标：** `Grid.useBreakpoint()` → `{ xs, sm, md, lg, xl, xxl }` 布尔值
+
+```typescript
+const screens = Grid.useBreakpoint();
+const isMobile = !screens.sm;                        // < 576px (仅 xs)
+const isTablet = (screens.sm || screens.md) && !screens.lg; // 576-991px
+const isDesktop = !!screens.lg;                      // ≥ 992px
+```
+
+影响范围：仅 `MainLayout.tsx` 一个文件，`useEffect` + `resize` 事件监听可移除。
+
+### 3.2 CSS 策略：antd Props 优先
+
+| 场景 | 优先方案 | 兜底方案 |
+|------|---------|---------|
+| 表格列过多 | `scroll={{ x }}` | 无（antd 自带滚动条） |
+| 卡片网格 | `Col` 响应式断点 props | `index.css` @media |
+| 文字截断 | `ellipsis: true` | `text-overflow: ellipsis` CSS |
+| 弹窗宽度 | antd `width` prop | `index.css` `max-width` 约束 |
+| 工具栏换行 | `flexWrap: 'wrap'` + `gap` inline style | — |
+
+**`index.css` 追加的 @media 规则（总计约 40 行）：**
+- `(max-width: 575px)`: 表格字体 13px、弹窗 max-width 约束、Modal body max-height
+- `(min-width: 576px) and (max-width: 991px)`: 平板特有的间距微调
+- 通用: `.ant-table-wrapper { overflow-x: auto }` 确保所有表格容器可滚动
+
+### 3.3 表格横向滚动
+
+所有 `<Table>` 统一添加 `scroll={{ x }}`。具体值：
+- 列少（≤6 列）：`scroll={{ x: 'max-content' }}` 或省略（antd 自动处理）
+- 列中（7-10 列）：`scroll={{ x: 800 }}`
+- 列多（>10 列或含长文本列）：`scroll={{ x: 1000 }}` 或更大
+
+操作列（最后一列）使用 `width` 固定宽度，必要时添加 `fixed: 'right'` 在宽表场景下提升体验。
+
+### 3.4 Dashboard 响应式网格
+
+```
+统计卡片 (4 张):
+  <Col xs={12} sm={12} md={6}>   // 手机2列 平板2列 桌面4列
+
+图表卡片 (2 张):
+  <Col xs={24} sm={12}>          // 手机堆叠 平板及以上并排
+```
+
+顶部工具栏（标题 + DatePicker）在小屏下从 `flex` 横向排列改为 `flexDirection: 'column'` 堆叠。
+
+### 3.5 ECharts 图表
+
+通过 `echarts-for-react` 的内置 `ResizeObserver` 自动适配：
+```tsx
+<ReactECharts
+  option={option}
+  style={{ width: '100%', height: isMobile ? 250 : 300 }}
+  opts={{ renderer: 'canvas' }}
+/>
+```
+容器宽度由 antd `Col` 响应式断点控制，图表自动跟随。甘特图动态高度逻辑不变（`Math.max(300, data.length * 40)`）。
+
+### 3.6 弹窗适配
+
+**全局 CSS（index.css）：**
+```css
+@media (max-width: 575px) {
+  .ant-modal { max-width: calc(100vw - 24px) !important; }
+  .ant-modal-body { max-height: 60vh; overflow-y: auto; }
+}
+```
+
+**组件级别：** 各弹窗 `width` 在桌面端固定值（400-600px），移动端由全局 CSS 覆盖为 `max-width` 约束。
+
+### 3.7 教室排期表
+
+最复杂的适配场景 — HTML `<table>` 含 31+ 日期列 + sticky 首列：
+- 外层 `div` 保持 `overflowX: 'auto'`
+- 首列（教室名）`position: sticky; left: 0` 保持已有
+- 日期列 `minWidth: 26` 不压窄
+- `overflowX` 容器在平板/手机下自动出现横向滚动条
+
+### 3.8 学生字段拆分
+
+学生管理页将 `{ title: '学号/身份证', dataIndex: 'idNumber' }` 一列拆为两列：
+```typescript
+{ title: '学号', dataIndex: 'studentNumber', width: 120, ellipsis: true },
+{ title: '身份证', dataIndex: 'idNumber', width: 180, ellipsis: true },
+```
+向后兼容：若后端暂未返回 `studentNumber` 字段，该列显示 `-`，不报错。
+
+## 4. 实现顺序
+
+```
+Phase 1: 基础
+  1. index.css 三断点体系
+  2. MainLayout useBreakpoint 重构
+
+Phase 2: 高优先级页面
+  3. Dashboard (4 张统计卡 + 3 张图)
+  4. 学生管理 (表格 + 字段拆分)
+  5. 入住管理 (表格 + 弹窗多)
+
+Phase 3: 批量页面
+  6-17. 剩余 12 个表格型页面（模式统一，效率高）
+
+Phase 4: 收尾
+  18. 教室排期表（特殊 HTML table）
+  19. 登录页（单卡片）
+  20. 全局验证
+```
+
+## 5. 验证计划
+
+- **视觉检查：** Chrome DevTools 响应式模式 → 375 / 768 / 992 / 1440 四个宽度
+- **每个页面检查：** 表格有无横向滚动 → 按钮是否错位/溢出 → 弹窗是否出屏 → 文字是否截断
+- **编译检查：** `npm run build` 确保 TypeScript 无报错

+## Context
+
+恭学教育基地管理后台是一个基于 React 19 + Ant Design v6 的单页应用，服务对象为基地管理人员。当前前端仅有一个 768px 的移动端断点（`MainLayout` 中），且页面级适配不完整：多列表格无横向滚动、仪表盘卡片使用硬编码 `Col span`、弹窗无宽度约束等。管理场景中操作人员可能使用手机、iPad/平板、桌面电脑等不同设备，需要统一的三端响应式体验。
+
+**技术约束：**
+- 不引入新的 UI 依赖，保持使用 Ant Design v6
+- 不改动后端 API 和后端逻辑
+- 使用纯 CSS（`@media` queries）+ antd 响应式 props（`Row/Col` 断点、`Table scroll`）
+
+## Goals / Non-Goals
+
+**Goals:**
+- 建立统一的三断点体系：手机 `< 768px`、平板 `768-1024px`、桌面 `> 1024px`
+- 所有页面的 `<Table>` 在小屏下可通过横向滚动查看全部列
+- 仪表盘统计卡片在平板和手机端自动调整列数
+- 登录页在手机上不溢出
+- 弹窗在所有端侧不超出屏幕
+- ECharts 图表响应容器宽度变化
+- 学生管理页「学号/身份证」拆分为两列
+- API/数据获取层不变，仅改 UI 渲染层
+
+**Non-Goals:**
+- 不更换组件库或引入 Tailwind CSS 等新样式框架
+- 不做列响应式隐藏（表格列全部保留，靠横向滚动）
+- 不改变路由和权限体系
+- 不涉及服务端渲染或 SSR
+- 不添加视觉主题切换能力
+
+## Decisions
+
+### 1. 断点定义与 CSS 组织
+
+| 断点 | 范围 | 典型设备 |
+|------|------|---------|
+| `xs` (手机) | < 768px | iPhone、Android 手机 |
+| `sm` (平板) | 768px - 1024px | iPad 竖屏、小型平板 |
+| `md+` (桌面) | > 1024px | 笔记本、台式显示器 |
+
+**策略：**
+- 全局样式放在 `index.css`，使用 `@media` 规则
+- antd `Row/Col` 组件使用内置 `xs/sm/md/lg` 断点 props
+- 避免组件内联 style 中的固定像素值，改为 CSS class 或 antd 响应式 props
+
+**为什么不引入 CSS 变量/主题系统？**
+当前项目规模适中（~16 页面），引入 CSS 变量体系增加复杂度但收益有限。直接用 `@media` queries + antd 响应式 props 即可覆盖。
+
+### 2. 表格横向滚动策略
+
+**决策：** 所有 `<Table>` 统一添加 `scroll={{ x: 'max-content' }}` 或基于列宽计算的 `x` 值，移动端通过手指滑动查看全部列。
+
+**列宽优化：**
+- 操作列固定宽度（`width: 120-200`），配合 `fixed: 'right'` 可选
+- 数据列设置合理的 `width` 避免过窄或过宽
+- 使用 `ellipsis: true` 防止长文本撑开列宽
+
+**为什么不用 antd 的 `responsive` 列隐藏？**
+用户明确要求保留全部列、用横向滚动。管理后台数据密集场景下，隐藏列可能导致信息缺失。
+
+### 3. 布局与侧栏
+
+**桌面（> 1024px）：** 保持当前 `Sider` + 内容区布局，侧栏可折叠，content margin 24px。
+**平板（768-1024px）：** `Sider` 默认折叠（`collapsed: true`），减少侧栏占用宽度，content margin 16px。
+**手机（< 768px）：** 当前已有 `Drawer` 替代 `Sider`，content margin 12px。
+
+### 4. 仪表盘与图表
+
+统计卡片：
+```
+xs={12} sm={12} md={6}  // 手机: 2列, 平板: 2列, 桌面: 4列
+```
+图表卡片：
+```
+xs={24} sm={12}  // 手机: 堆叠, 平板及以上: 并排
+```
+
+ECharts 通过 `echarts-for-react` 的 `style={{ width: '100%' }}` 自动跟随容器宽度。
+
+### 5. 弹窗与表单
+
+- Modal 添加 `width` 在桌面固定（400-600），平板/手机使用百分比或 `max-width` 约束
+- 全局 CSS: `.ant-modal { max-width: calc(100vw - 32px); }`
+- Form 保持 `layout="vertical"`，天然适配窄屏
+
+## Risks / Trade-offs
+
+| 风险 | 缓解 |
+|------|------|
+| 表格横向滚动在手机上交互不直观 | 添加 `scroll={{ x }}` 后 antd 自动显示滚动条；操作列可用 `fixed: 'right'` 固定 |
+| ECharts 甘特图在窄屏可能挤缩 | 设置最小高度，必要时在容器上 `overflowX: auto` |
+| 教室排期表（31 天列）表格极宽 | 已有 `overflowX: auto`，优化列 minWidth 和 sticky 首列 |
+| 修改涉及文件多（~18 个），可能引入 layout 抖动 | 每个页面改动后手动验证；改动粒度小（CSS + props），回滚简单 |
+
+## Open Questions
+
+- 无。三端断点、表格策略、拆分字段均已与需求方确认。

+## Why
+
+管理后台当前仅在布局层有一个 768px 的移动端断点，大多数页面使用固定列宽、硬编码 `Col span` 和多列表格，导致在手机和平板上文字溢出、按钮换行错位、表格内容被截断。需要为手机（< 768px）、平板（768-1024px）、桌面（> 1024px）三个端侧做统一响应式适配，确保所有界面文字不溢出、不强制换行。
+
+## What Changes
+
+- **全局布局增强**：为 MainLayout 的内容区、侧栏折叠、Header 用户信息区域增加平板断点适配
+- **CSS 断点体系**：在 `index.css` 中建立三断点响应式体系（`@media` 规则），覆盖表格、卡片、按钮、弹窗等全局组件
+- **全页面表格适配**：为所有页面的 `<Table>` 添加 `scroll={{ x }}` 确保窄屏横向滚动，列宽优化防止数据截断
+- **仪表盘响应式**：将 `Col span={6}` 改为响应式断点（`xs/sm/md`），ECharts 图表跟随窗口 resize
+- **登录页适配**：登录卡片从固定宽度改为响应式最大宽度
+- **工具栏/搜索栏适配**：统一所有页面顶部操作栏的 wrap 和 gap 行为
+- **弹窗响应式**：所有 Modal 添加平板/手机下的最大宽度和高度约束
+- **排期表适配**：教室排期的大 HTML 表格优化列宽和滚动体验
+- **学生字段拆分**：将学生管理页的「学号/身份证」列拆分为「学号」和「身份证」两个独立列
+- 保持使用 Ant Design v6 组件库，不引入新的 UI 依赖
+
+## Capabilities
+
+### New Capabilities
+- `responsive-layout`: 管理后台三端（手机 < 768px / 平板 768-1024px / 桌面 > 1024px）响应式布局，包括全局 CSS 断点、布局适配、表格横向滚动、组件响应式行为
+
+### Modified Capabilities
+（无现有前端相关 spec，不需要 delta spec）
+
+## Impact
+
+- **受影响文件**: `apps/admin/src/` 下所有页面组件（16 个页面 + 1 个布局）、`index.css`、部分组件文件
+- **不涉及**: 后端 API、数据库 schema、部署配置、认证/权限逻辑
+- **风险**: 低——改动限于 CSS 和组件 props，不涉及业务逻辑变更
