>Motion is critical for reorientation after transition.

The only case I can think of where this is true is on scroll, and that barely counts as animation. Anything else is an irritating waste of time.

The absolute worst offence is animating page content on scroll. Great job making me wait on pointless nonsense while scanning your website for the bit I'm looking for. People who do this should be sent to reeducation camps. Both for the animation, and for disregarding 'prefers-reduced-motion'.
