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.

Plymouth: bg-skull.svg is a 1920x1080 transparent composition but was rendered
at 300px and treated as a small centred logo, so the skull all but vanished and
the spinner (positioned off the logo height) landed on the monitor artwork. Now
render at native 1920px, scale to fill the screen, and pin the spinner at a
fixed 0.93 of screen height. Also fix DOTFILES_DIR (was off by one level, so the
bundled SVG never resolved and it fell back to a transparent placeholder) and
the dead ../plymouth.sh paths in plymouth-custom.sh and install-modules.sh.
Greeter: HyprLua now uses LightDM + lightdm-gtk-greeter, themed with the
existing cyberqueer GTK theme and a rendered skull background, via a new
self-contained lightdm module. ly is extracted from the DE scripts into its own
module so it stays installable; niri and legacy hyprland keep their inline ly.
Both greeters are registered in modules.conf as mutually exclusive, and the
generated installer/answerfile/docs regions were rebuilt from it. install-modules.sh
guards the 'ly' token with a padded match so it can't substring-hit 'p(ly)mouth'.
Add setup/tools/migrate-to-lightdm.sh to move an existing install (ly / greetd /
GDM / SDDM / LXDM) onto the Plymouth + LightDM setup: it disables the old DM for
the next boot only (never stops the running session) and delegates install +
theming to the module scripts. Supports --dry-run / --no-plymouth / --yes.
