With the pointer released, the helper still listed overlays by running vrcmd every second, a new SteamVR client each time, which kept SteamVR from going to standby. The list now pauses while the pointer is off. Starting the dev container from one of our services made that service own it, so stopping the service stopped the container and the desktop's compositor with it. scripts/container-up.sh starts the container in a systemd scope of its own before every distrobox enter.
