// Header for key system names. Keep these separate from some of our other
// EME utils because want to use these strings in contexts where other utils
// may not build correctly. Specifically at time of writing:
// - The GMP doesn't have prefs available, so we want to avoid utils that
// touch the pref service.
// - The clear key CDM links a limited subset of what normal Fx does, so we
// need to avoid any utils that touch things like XUL.
