I had an idea to embed a webpage in a dataurl and convert that to a QR code; the website would only exist on if you snapped the QR Code. I was dreaming of code-golf, demoscene, nft and weird business card applications, but the web-browsers ruined my fun because they won't display dataURL unless you manually copy/paste it into the URL bar.

Good idea. Built https://srv.us/d that does (edited):

    <html><body><script>document.body.innerHTML = decodeURI(window.location.hash.substring(1))</script></body></html>
So you can point to https://srv.us/d#<h1>Demo</h1>

Almost, page doesn't have a body yet, so you get a null ref. I thought of spinning it up or hosting on ipfs, but it still won't live forever, somebody will lose interest and stop paying the DNS costs or similar.

Fixed, thanks! Yes, longevity is an issue with anything online. On the other hand, in this case recovery is not a huge issue for anybody technical enough.

I was thinking at first it would be better if it takes the entire webpage as a datauri instead of the raw html like this basic business card template:

but that's already about half the max bytes for a QR Code, so maybe its not really that interesting.

There's no need to base64 encode HTML, since it's already plaintext. You can just omit the encoding declaration in the data URL and include the raw HTML, e.g. 'data:text/html,<html><body><h1>Hello, world!</h1></body></html>'. That should save a bit of overhead.
