Just when I thought I was done tinkering with my site I found NextJS. Oops.
I mean, I don't need an excuse to tinker with things that are better left alone. I apparently derive great joy from experimenting with static-site-generators including hugo and gatsby and metalsmith. Before that, I had a lot of fun playing around with seemingly every open source PHP-based CMS in existence. My bookshelf is full of blank books that have one page written in them before I moved on to something else because the current notebooks just weren't good enough for some reason. I re-arrange my office once a year or so. Just to put all this in context.
I believe my site is at the point where I can simply write into various Markdown files and have what I expect show up where I expect it now.
And if I need more custom functionality it's only a few JS lines away from working across my entire site.
