ui-motion-interaction

Provides the motion hub for UI design engineering: tactile state transitions (hover, active, focus-visible, drag, disabled), pointer physics (spotlight gradients, magnetic pull, 3D tilt), the Accot-Zhai steering law for hover corridors, Dan Saffer's micro-interaction lifecycle, canonical duration bands and spring tokens (stiffness, damping, damping ratio, overshoot), interruption and retargeting behaviour, rendering performance for animation (compositor-friendly properties, forced layout, will-change, INP) and reduced-motion handling. Use when crafting interactive components, defining design system motion tokens, choosing between easing and springs, or auditing animation smoothness and motion accessibility.

Bundled with Coacus. Its trust score, security findings and other files are on the plugin page.
