- One wizard question: "single user, no password, like SteamOS" switches to SDDM (autologin via CachyOS's own steam-set-session, no workarounds) and removes lock screen, user switching and log out (launcher shows only Sleep/Restart/Shut Down; Meta+L and Ctrl+Alt+Del unbound). Declining keeps the current login manager and KDE's defaults - Look up the newest steamdeck-kde-presets from Valve's release repos and verify its SHA-256; take over the new SteamOS 3.9 defaults - Restart plasmashell through systemd so the desktop keeps the session's dark theme; drop the bundled icon in favour of Valve's and Steam's - README and AGENTS.md updated
