Webmentions in Eleventy

In the interest of continuing to repeat myself I'm writing, once again, about adding webmentions to a blog.

Adding client-side rendered webmentions to my blog

My blog is currently hosted on weblog.lol which allows for a simple and configurable weblog managed in git with posts formatted in markdown. I wanted to add webmentions to my blog which, as of now, doesn't include a build step. To accomplish this, I've added an intermediary api endpoint to the same Next.js app that powers my /now page.
