Quick layman explanation on Frame:
- You create site, site has link
- Site has meta frame tags
- You post site link to FC client
- Client parses the meta tags
- If supported, will embed the Frame, if not fallback to simple embed
- Click Button will send POST to site link
- Response from site is HTML with new frame

Can you be a degenerate king, and show how it works in a thread?

Is it just an in-line I-frame that shows the result after an interaction happens?

Interesting. I guess JS theoretically could introduce security risks or vulnerabilities?

Unfortunately not (which would have been much more flexible in terms of what you can do with the content). The embed, changes the image on refresh depending on the response on button click.

Looking at the docs, you will need an API server that handles the POST request if you want button clicks functionality...
