Key files

etc/os-release

Identifies the system as “Antergos NeXT” to tools, installers, and the login manager.

etc/pacman.conf

Adds the [antergos-pkgs] custom repo so installed systems can receive updates.

etc/sddm.conf.d/kde_settings.conf

Sets the SDDM session to plasma.desktop (Wayland) by default.

etc/skel/.config/autostart/antergos-wallpaper.desktop

Runs the wallpaper setter on first login. Uses X-KDE-autostart-phase=2 to run after Plasma has initialized.

usr/local/bin/set-antergos-wallpaper.sh

Applies the wallpaper via plasma-apply-wallpaperimage and creates ~/.config/antergos-wallpaper-set marker to prevent re-running.
