Every page listed below is available as Markdown. Request the page URL with the header `Accept: text/markdown` and the response is the source Markdown, including frontmatter, instead of HTML. Appending `.md` to a URL does not work: those requests redirect to the HTML page, so content negotiation is the only route.
