Another improvement to make: the gallery card for the blog post, the markdown isn't rendered. So links show up as [link](url) I think my preference would be to strip the url from the preview, but having it render might be easier.

--- Done

Authorship isn't finding the metadata and just placing the GitHub handle. It would be nice to improve this.

@rowanc1 any insight on how to leverage the same functionality that allows blog posts to translate from author id to author metadata (in extended pythia.yml configuration file)?

[rowanc1]

The way your plugin is setup (I think) at the moment is that it is looking at just the metadata of the blog and isn't hooked into what myst knows about the author (pulling from inherited myst configs, etc.). When we move from a plugin to something that is more integrated with myst for the listings, I think that would improve — but I don't have specific advice at the moment unfortunately.

Thanks @rowanc1 I think what we have is fine for now, and we can look forward to it improving with the future built-in blog functionality.

This seems like a good "for now" solution until there's better MyST support for styled blogs.
