Offer a plain-text version of every page
Add _outputs/txt.jsx:
data({ contentType: "text/plain; charset=utf-8" });
`${page.title ?? page.date}\n\n${page.src}`
Every HTML page now has a .txt twin, /about beside /about.txt, holding
its title and raw source. Link it from the root layout:
{page.outputs?.txt && <a href={page.outputs.txt}>Plain text</a>}
Turn it off where it makes no sense with outputs: { txt: false } in a page's
frontmatter, or for a whole folder in its _defaults.jsx. See
Extra outputs per page
