Gah, please ignore the LSP formatter changes.

@agoose77 our existing CITATION.cff files use the convention

authors:
  - family-names: Rose
    given-names: Brian E. J.

Is that supported here? Or do we have to stick to name:?

I think the answer is here: https://mystmd.org/guide/frontmatter#frontmatter-authors

We can include

name:
   - surname: Rose
   - given: Brian E. J.

and some other fields as well.

I'm interested to see if myst can generate an equivalent to our existing CITATION.cff that would comply with Zenodo requirements. If so, we could automate the generation of the .cff file at build time and keep one version of truth for author details across all our many repos. That would be a win.

I think I meant to put these comments over in ProjectPythia/pythia-config#12, sorry!
