In PDF output, links are hard to notice
A link + link text in Markdown input is rendered in PDF output as link text, with a PDF link with the link. This works, but it's hard to notice the linkin PDF, and in some PDF readers (e.g., the reMarkable), not really possible to see. None of this is a problem in HTML output, where links are a first class thing.
Would it make sense, for PDF output, to have docgen modify the AST so that a) the link text is somehow emphasized (italic? bold? small caps?) and the link is given as a footnote (which Pandoc renders at the bottom of the page, by default)?
