Possible with GitHub Pages?

Imagine a pure client-only HTML/JS "GitHub Pages" app, e.g. https://microsoft.github.io/CSS-Exchange which is generated from https://github.com/microsoft/CSS-Exchange.

Is it possible to add copilot-sdk (or any AI feature) to such pure client-only HTML/JS "GitHub Pages" apps? Eventually, it is just Javascript that runs in the browser (client-side). Nothing is running/available at the server-side.
Not sure, how to communicate with Github Copilot CLI from javascript?

首先查看 copilot-sdk 的文档以及 issue 中提到的 GitHub Copilot CLI 集成点，然后将它们与纯客户端 GitHub Pages 应用的限制进行比较。确定仅在浏览器中运行的 JavaScript 是否可以直接使用 SDK 或 CLI，并记录受支持的集成路径或阻碍该集成的限制。
