On a headless KDE appliance the session has two outputs — run-headless-kde.sh's `kwin --virtual` bootstrap (where plasmashell draws by default) and our per-session streamed output — so the client saw only the wallpaper of an empty extended output (the KWin analogue of the GNOME/Mutter VIRTUAL_PRIMARY issue). New opt-in PUNKTFUNK_KWIN_VIRTUAL_PRIMARY: after creating the virtual output, set it primary via kscreen-doctor (KWin then re-homes the desktop onto it and disables the bootstrap), then belt-and-suspenders disable anything still enabled. The keepalive re-enables the bootstrap on teardown — though KWin also auto-re-enables it when our output is reclaimed, so there's never a zero-output window. Set in packaging/kde/host.env. Verified live on the Fedora 44 KDE box: mid-session the streamed output is the sole desktop at 0,0; post-session the bootstrap is back.
