The live session and installed system use a **video wallpaper** — `/usr/share/backgrounds/euri/euri-wallpaper.mp4` — played by the **Smart Video Wallpaper Reborn** Plasma plugin.
The video ships from the **`euri-layan-theme`** package (`depends=('kvantum' 'yakuake' 'euri-wallpapers' 'mpv')`). The same package installs the Smart Video Wallpaper Reborn plugin into the user's `~/.local/share/plasma/wallpapers/` from its `Configs/Home/` tree.
The `euri-wallpapers` package provides the still images:
- **euri-wallpaper.png** — the original Antergos wallpaper, sourced from the [Antergos/wallpapers](https://github.com/Antergos/wallpapers) repo. GPL-3.0.
Plasma overwrites `/etc/skel/.config/plasma-org.kde.plasma.desktop-appletsrc` on first login, so putting the wallpaper in skel doesn't work. Instead, a one-shot autostart script handles it:
1.`/usr/local/bin/set-euri-wallpaper.sh` — configures the Smart Video Wallpaper Reborn plugin (`luisbocanegra.smart.video.wallpaper.reborn`) via `qdbus6`, pointing it at `/usr/share/backgrounds/euri/euri-wallpaper.mp4` muted, then creates the marker file `~/.config/euri-wallpaper-set`
2.`~/.config/autostart/euri-wallpaper.desktop` (from skel, plus a copy in `/etc/xdg/autostart/`) — calls the script with `X-KDE-autostart-phase=2`
