Music

The product tour video uses Inspire Action by Yuri Megis (Wikimedia Commons), licensed under CC BY 4.0. The track is shorter than the two-minute tour, so it plays through and then repeats from the start, joined with a three-second crossfade; we added a fade-out at the end and adjusted the volume.
