Baking webmentions into the build

Back in 2022 I added webmention support to this blog. The implementation worked but it was entirely client-side, so the page would load, JS would fire, fetch from webmention.io, and render the results into the DOM. With JS disabled, on a slow connection, or in an RSS reader, the discussion section was just empty. It worked well enough that I didn’t touch it for three years, but for the last couple of weeks I’ve been doing some yak shaving.
