```js theme={null}
const res = await fetch('https://inplain.app/api/export', {
  method: 'POST',
  headers: {
    'content-type': 'application/json',
    'authorization': `Bearer ${PAT}`,
  },
  body: JSON.stringify({ kind: 'deck', format: 'pptx', source }),
});
const blob = await res.blob();
const url = URL.createObjectURL(blob);
window.location.href = url;
```

## 保真承诺

* `.pptx` → PowerPoint / Keynote / WPS 都能开
* `.xlsx` → formula 列转 Excel 公式(不是 baked 计算结果)
* `.pdf` → 浏览器打印 pipeline,字体保真
* `.docx` → Word / Pages 都能开
