logo placement

I need to unpack and investigate this for 1.9, after merging Pandoc template changes.

I need to file an issue / PR upstream for the page partial. There isn’t anything in Pandoc for logo, so this is otherwise unaffected.

I don’t know if we use the Typst page header or footer elsewhere; not in our .typ but it could be generated. Have to make sure we’re not stomping on something else.

The fact that parent populates a key rather than a value makes me think that validation is the most important part. I haven’t tried it but I imagine the error message if the value is not a key is not something we want to expose to users.

So I’ll create an issue for the validation of the other fields and then add parent.

Start by reviewing the pending Pandoc template changes and the page partial referenced in the discussion; inspect the .typ file and whether Typst headers or footers are generated elsewhere. Check how the other fields are validated, including parent, and confirm that logo placement and validation work without overwriting existing header or footer content.
