New x86_64 host for a 4th-gen Core i7 (Haswell) with a GTX 1070 8 GB,
wired to a television and driven with a Bluetooth controller.

Session: greetd gets an initial_session, so the machine autologins into
the gamescope Steam session at boot with no greeter and no keyboard.
Quitting Steam falls back to greetd's default_session (ReGreet), where
the ordinary Sway session is available for keyboard-and-mouse work.

Graphics: the GTX 1070 is Pascal, so it needs driver branch 580
(nvidiaPackages.legacy_580) like the Mac Pro's Quadro P400 -- the
nixpkgs default (production, 595.x) dropped Pascal support.

Games: RetroArch built through retroarch-bare.wrapper with 17 cores
covering NES through PS2, GameCube and Wii; Clone Hero; and Steam with
Proton-GE and protontricks. RetroArch's menu toggle is bound to L3+R3,
without which there is no way to exit a running core on a machine with
no keyboard.

Proton prerequisites beyond what programs.steam already arranges: the
esync file-descriptor hard limit is raised from systemd's default
524288 to 1048576 (soft limit untouched), and Proton-GE is wired in via
extraCompatPackages. vm.max_map_count already defaults high enough in
nixpkgs and needs no override.

Content lives in a shared /srv/games tree created by systemd.tmpfiles,
laid out one directory per system under roms/ using the libretro/ES-DE
naming convention, plus bios/, saves/, states/, a Steam library folder
and Clone Hero's songs. RetroArch is pointed at it declaratively.

hardware-configuration.nix is a placeholder, not a hardware scan: the
machine is not installed yet. It assumes partition labels `nixos` and
`BOOT` and must be replaced with nixos-generate-config output.
