+Limine, Noctalia Greeter and Plymouth appearance. Only Kanagawa is implemented
+so far; switching means selecting another module and rebuilding, not a live
+theme picker.
 Walker shares a compact layout with theme-provided colors: reduced padding,
 24px icons, clearer secondary text, and a smaller minimum window height.
 Limine's terminal background is fully transparent with no edge gradient so it
 does not obscure the wallpaper. Runtime appearance needs user verification.
-SDDM's purple-leaves theme and Plymouth's spinner are retained within Kanagawa;
-their visual redesign and the low-frame-rate boot animation remain open.
+Noctalia Greeter uses the same tracked green-leaves wallpaper, Lexend font,
+Phinger cursor and dark Kanagawa palette as the desktop. Its logo and scheme
+selector are hidden while power controls remain available. The pinned greeter
+does not expose Niri's pointer acceleration or touchpad settings, so those retain
+the greeter compositor defaults. Plymouth's spinner is retained; redesigning its
+low-frame-rate animation remains open. Runtime appearance needs user verification.
 Verification: flake evaluation and both workstation builds passed. A headless
 check of the built Neovim confirmed Kanagawa Wave, inactive-window dimming and
 the custom gutter setting. Rendered Herdr TOML, Walker XML and Limine settings
-also passed targeted checks. No system activation or live desktop changes performed.
