disko builds its format/mount script at install time; offline, the
script's tool closure (file, which, wrapper hooks) wasn't on the ISO and
nix tried to build it from source — which needs the network. Pre-building
one representative script (luks + swap variant) pins every input; the
user's actual invocation then differs only in the final text-generation
derivation, which builds offline in seconds.

Found by running the unattended install in an offline QEMU VM:
- compgen is missing from nixpkgs' non-interactive bash (the package
shebang) — replaced with plain glob tests in hardware-db and prewipe
- disko's eval resolves <nixpkgs> via NIX_PATH (a dead channel on the
ISO) and tried channels.nixos.org — export NIX_PATH to the pinned
nixpkgs source and point the flake registry at an empty baked file
- lock nomarchy by path (the source the ISO carries) instead of
git+https: git inputs clone even when narHash is known, which kills
offline installs; `original` keeps the forge URL so a later
`nix flake update` re-resolves normally. Works from dirty-tree ISOs too.

- LUKS2 is the installer default; in exchange the generated config sets
the new nomarchy.system.greeter.autoLogin (greetd initial_session) —
the disk passphrase already gates the machine.
- @snapshots subvolume + nomarchy.system.snapper.enable: hourly/daily
timeline snapshots of / and the nixos-rebuild-snap helper, ported from
the previous iteration (3bdfc35), guarded to no-op on non-BTRFS roots.
- @swap subvolume with a swapfile sized to RAM by default (disko
mkswapfile handles NOCOW); the installer computes the resume offset
and wires boot.resumeDevice + resume_offset for hibernation.

Ported from the previous iteration's installer (3bdfc35), adapted to the
mkFlake world. gum TUI: disk pick, optional LUKS2, user/hostname/timezone,
DMI → nixos-hardware autodetection (hardware-db.sh). disko partitions
GPT + 1 GiB ESP + BTRFS subvolumes; the generated machine flake lands at
~user/.nomarchy (one mkFlake call, /etc/nixos symlinks to it) and
nixos-install makes it bootable (UEFI/systemd-boot, v1 single disk).
Offline by construction: the target flake.lock is composed from the rev
the ISO was built from (compose-lock.py), `nix flake archive` seeds the
target store, and the ISO pre-builds the template system + desktop.
First boot lands themed: the HM generation is pre-activated in chroot.
mkFlake grows two things for this: hardwareProfile now also takes a list
(autodetection emits several common-* modules), and installed systems get
the standalone home-manager CLI from the pinned input. Unattended mode
(NOMARCHY_UNATTENDED=1 + env) documented in docs/TESTING.md §4.

Downstream users now own only system.nix and home.nix; their flake.nix is
generated once from the template and never hand-edited. mkFlake (lib.nix)
wires both layers and maps hardwareProfile = "<name>" to nixos-hardware
modules (new input, pinned here, nixpkgs follows ours; unknown names fail
with did-you-mean suggestions). Flake checks evaluate the template through
mkFlake — including a real profile — so drift fails `nix flake check`.
Also from the live-VM testing session: install the home-manager CLI in the
live ISO and pin flake inputs transitively (offline theme switching needs
stylix's own inputs too), plus swww→awww doc updates.

Found by booting the live ISO (docs/TESTING.md checklist):
- pin HM configType = "hyprlang" (26.05 stateVersion defaults to the new
Lua config and renders these settings as broken hl.$mod(...) calls,
booting Hyprland into emergency mode)
- drop dwindle:pseudotile (removed in Hyprland 0.55; aborts config parse)
- disable splash rendering alongside the logo
- launch awww-daemon and call awww with swww fallback (nixpkgs' swww is
the renamed awww fork; no `swww` binary exists anymore)

Full replacement of the previous iteration, rebuilt around three ideas:
- Pure evaluation: theme-state.json lives inside the flake and is read
via the nomarchy.stateFile option — no --impure, ever.
- All-Home-Manager theming: `nomarchy-theme-sync apply` writes the JSON
and runs `home-manager switch`; every theme change is one atomic,
rollbackable generation. Wallpaper (swww) is the sole runtime piece.
- Flat, downstream-first layout: modules/{nixos,home} with one
options.nix each, exported as nixosModules/homeModules + overlay +
flake template; system (nixos-rebuild) and desktop (home-manager
switch) rebuild paths are fully split.
Ships 21 themes imported from the previous iteration (palettes,
wallpapers, btop themes, six whole-swap Waybar identities), Stylix for
the GTK/Qt/cursor long tail, a live ISO target with offline theme
switching, and docs/TESTING.md with the QEMU verification workflow.
