为 SVG 路径或字体图形提供原生尺寸、颜色和语义。

本指南覆盖默认 Emotion 环境的 Material UI Core；扩展包与额外示例按清单单独标注。

## 使用场景与业务边界

SvgIcon／Icon 包装器不是整套图标目录；字体图标需要真实字体资源，装饰图标应隐藏语义。

## 原生组成与范围

`Icon`, `SvgIcon`

保持 Material UI 原生组合与类型，不替换为 JGuang／Base UI／Radix 同名 API。示例条目不是额外组件。

## 原生安装与初始化

```bash
npm install @mui/material@9.4.0 @emotion/react@11.14.0 @emotion/styled@11.14.1
```

采用原生 npm 包与 Emotion，不提供虚构的 JGuang UI Registry 地址。将示例放在原生 ThemeProvider 内，按项目选择 CssBaseline 或 ScopedCssBaseline。先检查 React、现有 Provider、锁文件与 SSR 配置；不要覆盖用户文件或忽略 peer 冲突。本批实际验收 React 19.2.8；React 18 及以下须匹配 react-is。完整初始化规则见随附的双语 setup 文档。

## 关键原生参数

仅解释本指南选出的关键参数，不是平铺的通用 API。原生继承来源、slot 结构、可空值与泛型仍按固定源码保留。

| 所属组件.属性 | 用途说明 | 声明来源 |
| --- | --- | --- |
| `SvgIcon.viewBox` | SVG 坐标系统，不是渲染后的 CSS 尺寸。 | `SvgIcon` |
| `SvgIcon.titleAccess` | 可访问 SVG 标题，装饰性 SVG 通常不提供标题并保持隐藏。 | `SvgIcon` |
| `SvgIcon.fontSize` | 原生图标尺寸枚举，与主题关联，不是通用任意尺寸 API。 | `SvgIcon` |
| `Icon.baseClassName` | 字体图标 CSS 类名，须加载真实匹配的字体资源。 | `Icon` |

## 可运行原生示例

下列机器键只选择示例入口，不会作为通用 variant 属性传入每个组件。原生示例 JSX 与数据保持上游原文；JGuang 编写的验收示例明确标注。

- 使用方法 · `SvgMaterialIcons` · 上游原生示例
- SVG 图标容器 · `SvgIconChildren` · 上游原生示例
- 颜色 · `SvgIconsColor` · 上游原生示例
- 尺寸 · `SvgIconsSize` · 上游原生示例
- 创建 SVG 图标 · `CreateSvgIcon` · 上游原生示例
- Material 字体图标 · `Icons` · 上游原生示例

## 尚未支持的额外示例

这些条目仍保留在上游清单中，不静默跳过，也不展示为已完成预览。需要补充依赖／框架验收后再纳入可运行列表。

- Font Awesome 字体扩展 · `FontAwesomeIcon`: `fg-loadcss`
- Font Awesome 字体扩展 · `FontAwesomeIconSize`: `fg-loadcss`

## 真实使用示例

固定版本的未修改原生示例；复制时同时保留所需的局部辅助文件。

```tsx
import Box from '@mui/material/Box';
import Grid from '@mui/material/Grid';
import Typography from '@mui/material/Typography';
import DeleteIcon from '@mui/icons-material/Delete';
import DeleteOutlinedIcon from '@mui/icons-material/DeleteOutlined';
import DeleteRoundedIcon from '@mui/icons-material/DeleteRounded';
import DeleteTwoToneIcon from '@mui/icons-material/DeleteTwoTone';
import DeleteSharpIcon from '@mui/icons-material/DeleteSharp';
import DeleteForeverIcon from '@mui/icons-material/DeleteForever';
import DeleteForeverOutlinedIcon from '@mui/icons-material/DeleteForeverOutlined';
import DeleteForeverRoundedIcon from '@mui/icons-material/DeleteForeverRounded';
import DeleteForeverTwoToneIcon from '@mui/icons-material/DeleteForeverTwoTone';
import DeleteForeverSharpIcon from '@mui/icons-material/DeleteForeverSharp';
import ThreeDRotationIcon from '@mui/icons-material/ThreeDRotation';
import FourKIcon from '@mui/icons-material/FourK';
import ThreeSixtyIcon from '@mui/icons-material/ThreeSixty';

export default function SvgMaterialIcons() {
  return (
    <Box sx={{ flexGrow: 1 }}>
      <Grid container sx={{ color: 'text.primary' }}>
        <Grid size={4}>
          <Typography>Filled</Typography>
        </Grid>
        <Grid size={8}>
          <DeleteIcon />
          <DeleteForeverIcon />
        </Grid>
        <Grid size={4}>
          <Typography>Outlined</Typography>
        </Grid>
        <Grid size={8}>
          <DeleteOutlinedIcon />
          <DeleteForeverOutlinedIcon />
        </Grid>
        <Grid size={4}>
          <Typography>Rounded</Typography>
        </Grid>
        <Grid size={8}>
          <DeleteRoundedIcon />
          <DeleteForeverRoundedIcon />
        </Grid>
        <Grid size={4}>
          <Typography>Two Tone</Typography>
        </Grid>
        <Grid size={8}>
          <DeleteTwoToneIcon />
          <DeleteForeverTwoToneIcon />
        </Grid>
        <Grid size={4}>
          <Typography>Sharp</Typography>
        </Grid>
        <Grid size={8}>
          <DeleteSharpIcon />
          <DeleteForeverSharpIcon />
        </Grid>
        <Grid size={4}>
          <Typography>Edge-cases</Typography>
        </Grid>
        <Grid size={8}>
          <ThreeDRotationIcon />
          <FourKIcon />
          <ThreeSixtyIcon />
        </Grid>
      </Grid>
    </Box>
  );
}

```

## 示例依赖边界

`@mui/material/Box`, `@mui/material/Grid`, `@mui/material/Typography`, `@mui/icons-material/Delete`, `@mui/icons-material/DeleteOutlined`, `@mui/icons-material/DeleteRounded`, `@mui/icons-material/DeleteTwoTone`, `@mui/icons-material/DeleteSharp`, `@mui/icons-material/DeleteForever`, `@mui/icons-material/DeleteForeverOutlined`, `@mui/icons-material/DeleteForeverRounded`, `@mui/icons-material/DeleteForeverTwoTone`, `@mui/icons-material/DeleteForeverSharp`, `@mui/icons-material/ThreeDRotation`, `@mui/icons-material/FourK`, `@mui/icons-material/ThreeSixty`, `@mui/material/SvgIcon`, `@mui/material/Stack`, `@mui/material/colors`, `@mui/material/utils`, `@mui/material/Icon`, `@mui/material/styles`

直接导入 Icons／System／Utils 的示例需要匹配 9.4.0 包。局部数据与辅助文件属于示例闭包，不是额外组件。远程图片和模拟操作不提供后端。

## 原生源码声明

声明与 import 从固定源码提取，不平铺联合类型或外部继承。英文注释／类型属于原始源码参考，不代表上游正文已全文翻译。共享类型仍位于原生包中。

## 安装后验收

执行严格类型检查、生产构建和实际交互。检查键盘标签／焦点、原生支持的禁用／错误／只读语义、深浅色、窄屏和减少动画。按真实宿主数据检查回调，不把复制提示词当作安装完成。初始化工具还需检查服务端 HTML 与无告警水合。
