+## mpv + ModernZ OSC
+
+Videoplayer ist `mpv` mit [ModernZ](https://github.com/Samillion/ModernZ) als OSC, Thumbnails via thumbfast:
+- `mpv-modernz-git` liefert `modernz.lua` + Font + Default-Config nach `/etc/mpv/`
+- `mpv-thumbfast-git` liefert `thumbfast.lua` nach `/etc/mpv/scripts/` (wird von ModernZ automatisch erkannt)
+- `defaults/etc/mpv/mpv.conf` deaktiviert Stock-OSC (`osc=no`) und Titelleiste (`title-bar=no`)
+- `defaults/etc/mpv/script-opts/modernz.conf` überschreibt die Farben auf Catppuccin Mocha (Lavender als Accent, matcht waybar/swaync)
+- Deploy via moonarch-git: staging nach `/usr/share/moonarch/mpv/`, `post_install` kopiert nach `/etc/mpv/` (modernz.conf wird dabei gegenüber dem AUR-Default überschrieben — gleiches Pattern wie foot.ini/waybar style.css)
