# Nix flake + direnv integration
#
# Plain direnv re-evaluates the flake on every shell entry, which can be quite slow (~5-10s).
# nix-direnv caches the evaluation as a Nix GC root so subsequent
# loads are near-instant. If the developer doesn't have nix-direnv installed
# globally, we fetch it once (hash-verified) and cache it in ~/.config/direnv/.
# See: https://github.com/nix-community/nix-direnv
