# punktfunk headless KDE Plasma session — systemd USER unit.
#
# Brings up `kwin --virtual` on WAYLAND_DISPLAY=wayland-kde plus the full Plasma desktop
# (portals, polkit agent, a supervised plasmashell) via run-headless-kde.sh, so the punktfunk
# host's *kwin* backend can stream the live desktop. This is what makes a headless box a
# self-contained streaming appliance: no display manager, no login, no manual script — the
# session comes up at boot. Pair it with punktfunk-host.service (kwin backend) + linger.
#
# The script foregrounds on `wait $KWIN_PID` and re-spawns plasmashell for KWin's lifetime, so
# Type=simple + Restart=always keeps the desktop alive (a KWin crash brings the whole session
# back). It sets its own env (XDG_CURRENT_DESKTOP=KDE, WAYLAND_DISPLAY=wayland-kde,
# XDG_MENU_PREFIX=plasma-, …) — see run-headless-kde.sh.
#
# Appliance install (boot with no interaction):
#   cp scripts/punktfunk-kde-session.service scripts/punktfunk-host.service ~/.config/systemd/user/
#   cp scripts/host.env.example ~/.config/punktfunk/host.env   # edit for the kwin backend
#   systemctl --user daemon-reload
#   systemctl --user enable punktfunk-kde-session punktfunk-host
#   sudo loginctl enable-linger "$USER"   # <-- starts user units at boot WITHOUT a login
#   reboot                                #     (or: systemctl --user start … to bring up now)
