# Chromium kiosk window pointed at identity's dashboard.html — weather + what-to-
# wear, who's home, groceries running low. Installed to /usr/local/bin/home-kiosk.
# Called both at session start and by door-panel-agent on a "Show home" MQTT command.
#
# Same kill-and-relaunch shape as hosts/kitchen-display's pantry-kiosk. Kills ANY
# chromium instance before launching (not just its own profile) — this device has
# only one workspace, same reasoning as hosts/kitchen-display's pantry-kiosk/
# identity-kiosk pair (see that host's README for the full explanation).
