        Snapper-driven BTRFS timeline snapshots of `/`. Auto-disables when

        a "Pre-rebuild" snapshot before each switch.

        suspend-then-hibernate (lid close, idle, power button). NOTE: this

        zRAM alone is not enough.

        fcitx5 input method (CJK / IME). Wires NixOS's i18n.inputMethod and
        autostarts fcitx5-daemon. Adds a small footprint when enabled, so
        most users want this off.

        voxtype voice-typing integration. NOTE: voxtype is not packaged in
        nixpkgs — when enabled, install voxtype yourself (e.g. via
        `home.packages = [ (pkgs.callPackage … {}) ]`). With this off the
        SUPER+CTRL+X keybinding and waybar widget are no-ops.
