Initialising…
Record: launch a session from the XR control panel,
move around, then exit. Each session is saved as a new recording
below. Play replays a recording in an emulated headset (no
hardware needed); Save downloads it as JSON; Delete
removes it. Add ?recording=<path> to the URL to
play a recording fetched from the example-data server.
Note that playback still requires IWE extension since we currently dont use iwer/devui.
