1//! Motion atoms: one enter or exit leg of a presence transition.
2//!
3//! Each [`MotionAtom`] maps to a CSS keyframe family (`orbital-motion-fade`, `orbital-motion-scale`,
4//! `orbital-motion-slide-*`, etc.). Pair atoms with [`crate::PresenceMotion`] for enter+exit presets,
5//! or compose manually via [`PresenceMotion::new`](crate::PresenceMotion::new).
