引用来源用于内容展示场景。下面的官方示例展示原生用法与状态，属性名保持上游 API。

## 安装与前置条件

```bash
npm install @astryxdesign/core@0.7.1 @astryxdesign/theme-neutral@0.7.1 @stylexjs/stylex@0.19.0
```

需要 React 19+，按顺序导入基础 CSS 和主题，并设置 Theme Provider。参见[开始使用](/resources/astryx/docs/getting-started)。

## 示例与使用方式

- **引用来源 · 综合展示 1**：首先体验这个示例，再查看代码理解组件的组合方式。
- **引用来源 · 交互示例 2**：可交互查看这一用法的行为，复制代码时保留它实际使用的属性与导入。

## API 与上游详细参考

优先使用 0.7.1 官方中文说明；上游尚未提供中文的条目保留英文。属性名、类型及默认值保持原生 API，不把示例状态名称当成组件属性。

## Citation

Citations display inline references to external sources. Use them to attribute information within AI-generated responses, articles, or anywhere provenance and source links are needed.

| 属性 | 类型 | 默认值 | 说明 |
|---|---|---|---|
| source * | CitationSource |  | The citation source object containing title, url, an optional image src, and an optional icon node. The url follows the shared navigation rule described on the Link `href` prop; rejected destinations leave the citation visible without navigation. Image src uses separate resource handling. |
| number * | number |  | The display index for this citation. |
| variant | 'label' \| 'number' | 'label' | Display style: a label chip showing the source title or a compact numbered badge. |

### 使用建议

- Use the label variant when the source title adds meaningful context for the reader.
- Use the number variant for compact inline references within body text, like footnotes.
- 避免：Mix label and number variants in the same paragraph. Pick one style per context for visual consistency.

### 主题 API

```json
{
  "targets": [
    {
      "className": "astryx-citation",
      "visualProps": [
        "variant"
      ]
    }
  ]
}
```

### 组件结构

- **Container**: The root wrapper. Accepted source URLs render an anchor; missing or rejected URLs render an inert span.
- **Icon**: An optional source icon shown before the label text. Accepts a favicon/logo image URL (via source.src) or a React node such as an Astryx <Icon>. Only available in the label variant.
- **Label text**: The source title, truncated with ellipsis when it exceeds the max width. Shown in the label variant.
- **Number**: The citation index displayed as a superscript badge. Shown in the number variant.
