Enum MotionPreference 

pub enum MotionPreference {
    Full,
    Crossfade,
    Snap,
}

How much of the described motion actually runs.

Resolution follows the crate’s customization order: this default → the application’s installed policy → per-surface overrides where a component exposes one. The OS reduce-motion signal composes with the policy and can only restrict: under reduce motion the effective preference is at least Crossfade, never less — the policy may choose Snap, but nothing wins motion back from the OS signal.

Variants

Full

Everything the policy describes: travel, springs, and loops.

Crossfade

Comprehension-aiding opacity only, at the quick tempo: no travel, no springs, no stagger delays, and no repeating loops beyond progress indication.

Snap

State changes land in one frame.
