Animation

slidemotion exposes low-level animation primitives for custom components.

Core utilities

• interpolate for mapping progress ranges
• spring and springDuration for physical motion
• easing helpers from slidemotion/animation
• createAnimationLoop, tweenMode, springMode for custom drivers

Step-aware animation

Use useStepProgress() or useStep() when you need custom motion logic.

const progress = useStepProgress();
const opacity = interpolate(progress, [0, 1], [0, 1]);

Enter and exit choreography

Animate and the built-in transition components now support backward exits. That makes reverse navigation feel intentional instead of abruptly unmounting content.
