 and `flakes` experimental features. The committed `flake.lock` pins nixpkgs and
 its Rust toolchain; package evaluation checks that compiler against the Rust

+On macOS (`aarch64-darwin`), none of this applies: winit talks to AppKit, wgpu renders through

 On another distribution, graphics drivers outside the Nix store may need a
 matching [nixGL wrapper](https://github.com/nix-community/nixGL). Follow its
 GPU-specific instructions; a wrapper for a different driver is not a substitute.
