6/// the `change` listener from the browser's `MediaQueryList`.

8/// A `true` answer means the user asked the operating system to
9/// minimise animation, and the UI should replace motion with a
10/// cross-fade. The global stylesheet already honours the preference for
11/// its own transitions; this handle exists for the component-level
12/// decisions a stylesheet cannot make.
