Without -d, cage never negotiates xdg-decoration, so GTK4/ReGreet falls
back to drawing its own client-side title bar chrome on some machines.

Diagnosed the intermittent "login won't take input / frozen cursor" on this
dual-AMD-GPU box: cage (wlroots) could pick the display-less iGPU, and amdgpu
hardware cursors can freeze. regreet-session.sh now:
- pins WLR_DRM_DEVICES to the first DRM card with a connected output (portable,
evaluated live — no hard-coded PCI path),
- sets WLR_NO_HARDWARE_CURSORS=1 (fixes the stuck cursor),
- runs cage with `-m last` so the login card centres on a single monitor instead
of the default "extend", which stretched the canvas across all three monitors
and left the card floating in the middle of the span.
sysupdate.sh now deploys /etc/greetd config (config/regreet/session, not PAM) when
greetd is the active greeter, using the single primed sudo credential.

Replace the Xorg lightdm-gtk-greeter with a wlroots-native greetd + ReGreet
greeter (inside a cage kiosk), fixing three issues rooted in running an X
greeter on a multi-monitor / HiDPI / Wayland box: a blank output, tiny
scaling, and the Xorg->Wayland VT/seat handover race that left the Hyprland
session with dead keyboard/mouse.
- etc-greetd/: greetd config, ReGreet config (cyberqueer GTK4 theme, larger
font, wallpaper background), cage session launcher, and a password + FIDO
PAM stack (no securetty/OATH, which a graphical greeter cannot drive).
- greetd-regreet.sh: install/enable module, mutually exclusive with the
lightdm and ly greeter modules.
- Greeter background tracks the desktop wallpaper: a root systemd .path unit
mirrors the picker's choice to a greeter-readable path (the user's home is
0700, so the unprivileged greeter cannot read it directly).
The LightDM path is kept as a dormant alternative and hardened en route:
pam_u2f (FIDO) added to its PAM stack, a HiDPI + multi-monitor
display-setup.sh, a larger greeter font, and the same wallpaper-sync units.
