Nice, I'd like to follow this. I tried browsing there with EWW, but I'm blocked by an "Enable JavaScript" message. This seems to be a Mastodon 4.x thing; 3.5.x servers work great in EWW (read-only at least). I'm hoping there's some ?nojs=1 type workaround that I haven't found yet. I wrote a blog post about this just the other day: https://www.fitzsim.org/blog/?p=465
