[Question]: Tldraw as a complete application
### What's the example?

This is rather a question. Firstly thanks for this awesome library. My question is, what is the proper way to use tldraw as a standalone and solid application rather than a library to import somewhere?

If I'm not wrong, "File > Save" and "File > Load" functionalities are not open source. So is there a third-party that you know of who implemented such features and released it? My Google search didn't bring up useful results. So I'm clueless here, as a non-js-developer.
