- thermald on the x86 hosts (guarded; the Asahi MBP self-governs).
- T400 battery charge thresholds (75/80) via tp_smapi; tlp itself comes
from the nixos-hardware profile.
- Bluetooth (bluez + powerOnBoot) and blueman on the laptops — the MBP
already loads Apple BT firmware but bluez was never running.
- earlyoom + fwupd on the physical graphical hosts; zram on the Mac Pro.

- common-nixos: nix.settings.auto-optimise-store + larger download buffer.
- workstation: fstrim, boot.tmp.cleanOnBoot, and the shared graphical
options moved here from the per-host configs (pipewire, swaylock PAM
stub, redistributable firmware) -- MBP-Asahi gains audio it lacked.
- T400: zramSwap for the low-RAM host.
- MBP-Asahi: nixos-apple-silicon binary cache substituter.
- MacPro31 README: describe the real (LVM/UUID) hardware config; it is no
longer a placeholder.

Document the greetd/ReGreet greeter in the top-level README and the T400
and Mac Pro install notes, including that the user account needs a
password set before the greeter can authenticate.

Add system/machine/{T400,MacPro31}/README.md covering the placeholder
hardware-configuration regeneration, partition labels, bootloader selection
(T400 boot variants; Mac Pro EFI quirks), and GPU notes. Link each from its
configuration.nix header, and refresh the top-level README host table (T400
replaces X1, Mac Pro 3,1 added) with links to both.

Split the T400 bootloader into self-contained, importable modules so the host
can match whatever firmware is flashed (switch by changing one import):
- boot-bios.nix stock BIOS / coreboot+SeaBIOS -> GRUB on the MBR (default)
- boot-coreboot-grub.nix coreboot GRUB payload -> config-only GRUB (device=nodev)
- boot-coreboot-uefi.nix coreboot Tianocore/UEFI payload -> systemd-boot; carries
its own ESP (/boot vfat) so it travels with the mode
Cover the optional discrete ATI Mobility Radeon HD 3470 (RV620): load the open
`radeon` KMS driver in the initrd for early modesetting (firmware via
enableRedistributableFirmware), with a note on the T400's switchable graphics.
All three boot variants evaluate; nixfmt clean.

- lyrathorpe-t400 replaces lyrathorpe-x1c: ThinkPad T400 (legacy BIOS -> GRUB,
Intel microcode + redistributable firmware for iwlwifi, pipewire, sshd).
- lyrathorpe-macpro31: new desktop host (portable = false) importing
desktop.nix. Mac Pro 3,1 has 64-bit EFI -> systemd-boot; wired NetworkManager
via desktop.nix; desktop status bar (temperature + net, no battery).
Both ship hand-written placeholder hardware-configuration.nix (root/swap/ESP by
label, GRUB device /dev/sda) to be regenerated with nixos-generate-config and
committed at install time. All five host configs evaluate; nixfmt clean.
