The videos look awesome but the "try it out here" codesandbox links don't work for me on MacOS Chrome desktop. I get 'Uncaught ReferenceError: SharedArrayBuffer is not defined' and some CORS errors: 'ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep'.
You have to open the previews in a dedicated tab as codesandbox's inline editor blocks the header from being set. It also may get blocked if you are using a privacy focused browser.
I'll try to include embedded examples in the future.
