Select the CachyOS kernel per-Host via boot.kernelPackages, enable Intel microcode and redistributable firmware (ath10k for the QCA6174 wifi), and move zram behind a toggle Module. Declare the chaotic binary cache in the base Nix settings (extra-substituters/keys) so the built system fetches the kernel from nyx-cache rather than compiling it.
