FWIW, the earlier test of this which used the favicon looked better in
slack (except the overly puny resolution, of course). See attached.

https://ogp.me/ suggests theres
og:image:width - The number of pixels wide.
og:image:height - The number of pixels high.

no idea if that's in relation to the sizing of the preview or the actual

Not sure they ever do. But I am also not clear whether the right tag is
og:article:author, or article:author. Actually kind of seems the latter.
