This file is for https://github.com/nix-community/nix-direnv / direnv.net to load the shell once you cd into the directory. Requires first-time approval.

This is how this shows up. Doesn't work if you use direnv and the shell is cached, but it's something.

This is just for local usage, I did a POC of using the same shell with the same versions in CI (#68) but it only proved my fears - it takes too long for the initial setup so it doesn't really improve the situation much, regardless of how good Nix is at caching (ephemeral runners don't help).
