+### Noctalia Lockscreen & PAM Setup
+
+On Ubuntu, the Noctalia uses PAM (`login` service) and expects the shadow helper at `/run/wrappers/bin/unix_chkpwd`. Because `/run` is a `tmpfs` (cleared on reboot), use `systemd-tmpfiles` to recreate the symlink automatically on every boot:
+Also the Ubuntu PAM configs use Debian-specific @include macros, which the upstream Linux-PAM library inside the Nix package does not support.
+
+```bash
+printf "d /run/wrappers/bin - - - -\nL+ /run/wrappers/bin/unix_chkpwd - - - - /sbin/unix_chkpwd\n" | sudo tee /etc/tmpfiles.d/nix-wrappers.conf > /dev/null
+sudo systemd-tmpfiles --create /etc/tmpfiles.d/nix-wrappers.conf
+```
+
+```bash
+sudo cp -n /etc/pam.d/login /etc/pam.d/login.bak
+printf "auth    sufficient pam_unix.so try_first_pass nullok\nauth    required   pam_deny.so\naccount required   pam_unix.so\nsession required   pam_unix.so\n" | sudo tee /etc/pam.d/login > /dev/null
+```

+# Noctalia
+
+Noctalia is the desktop shell for the Hyprland profiles. Hyprland remains the compositor and window-management layer; Noctalia provides the panel, application and emoji launcher, notifications, session actions, wallpapers, lock screen, idle manager, clipboard history, tray, OSD, and control centre.
+
+The dock is deliberately disabled.
+
+## Configuration model
+
+`modules/home/desktops/noctalia/default.nix` is the declarative baseline. Noctalia's Settings UI may store user-level overrides in its state directory; these survive rebuilds. The shipped baseline is reapplied only when the Home Manager configuration changes.
+
+Zion also enables Noctalia Greeter through Greetd. Firefly uses the shell role only because it is configured as a Home Manager-only profile.
+
+## Migrated components
+
+| Previous component | Noctalia replacement |
+|---|---|
+| Waybar | Top bar: launcher, workspaces, clock, tray, system monitors and quick controls |
+| Fuzzel and Rofi Emoji | Launcher with application, calculator, emoji, wallpaper and window providers |
+| SwayNC | Notification daemon and notification history |
+| Wlogout | Session panel with lock, hibernate, logout, suspend, shutdown and reboot actions |
+| Hyprpaper | Native wallpaper service |
+| Hyprlock | Native lock screen |
+| Hypridle | Native idle manager |
+| NetworkManager and Blueman tray applets | Noctalia control-centre widgets and tray |
+| Pavucontrol | Noctalia audio controls |
+| Grimblast package | Noctalia screenshot service |
+
+Noctalia additionally enables clipboard history, screen time, per-output wallpapers, a system monitor, calendar, scheduled night light, brightness OSD, and a Windows-reboot session action on Zion.
+
+## Wallpaper migration
+
+A one-time user service transfers the legacy Hyprpaper assignments after Noctalia starts. It records completion in `$XDG_STATE_HOME/noctalia/.wallpapers-migrated-v1`, so subsequent rebuilds preserve changes made through Noctalia.
+
+| Previous output selector | Wallpaper |
+|---|---|
+| `eDP-1` | `anime-city.jpg` |
+| `DP-1` | `gohan-supersaiyan.png` |
+| Dell `AW2725Q G2QC174` | `luffy-gear-5.jpg` |
+| Samsung `LC27G7xT H4ZNC00167` | `one-piece-logo.jpg` |
+| fallback | `minimal-space.jpg` |
+
+Remove that marker only when the declarative migration should be run again.
+
+## Shell shortcuts
+
+| Key | Action |
+|---|---|
+| `Super+E` | Toggle launcher |
+| `Super+P` | Toggle session panel |
+| `Super+N` | Open notification controls |
