No, I use a Python-based static site generator so I essentially generate a new page for each tag, populated with links to the posts containing that tag.

I see! This would be the standard server side / pre-rendered approach. I somehow thought you did a client side solution w/o JS.

That would be interesting, if it was possible to do it in a minimal way!

What is your automated deployment pipeline for this kind of website?

I write posts in an editor (presently nvim), generate the site, and have a git hook that basically publishes it to neocities along with pushing it to my repository. It's very much a tiny hobby blog so I haven't put much effort into the whole process.
