Coding page not properly served by Gitlab
As mentioned on the Reddit thread, there seems to be an issue with the coding page on reload throwing a 404 (or if you directly visit https://whatcanidofor.archlinux.org/coding/).
I spent a few minutes trying to fix this and I noticed in the build, there's both a coding.html and a coding folder (but no coding/index.html), so maybe this is an issue with how svelte-kit exports pages when there's both a single page and a folder with the same name, mixing with how gitlab serves those requests. I've got an experimental branch (which I'll submit soon) which tweaks generation a bit and forces index.html files to be used, which makes the generated code a little more messy, but it should work with gitlab pages, so it's probably worth it.
