amvcp-anim-ambient-hover

Reduced-motion safe ambient hover animations are added using token-driven CSS classes like va-float-y, va-breathe, and va-tilt, managed by a small JS runtime that pauses loops via IntersectionObserver. This ensures decorative motion remains intentional and accessible without distracting from content.

Skeleton loading placeholders for streaming content are implemented using dedicated CSS utility classes such as va-skeleton and va-pulse. These classes provide shimmering visual states that indicate asynchronous loading, ensuring users understand content is actively streaming or loading.

CSS utility classes handle 3D card tilt and link hover polish by applying predefined token-driven styles such as va-tilt for interactive cards and va-link for animated link underlines. These classes trigger smooth visual affordances on hover without requiring complex custom JavaScript.

This ambient animation system expects the amvcp-animation.js foundation contract to manage its JavaScript runtime and IntersectionObserver loop pausing. While it has no listed package dependencies, it requires this specific animation foundation to enforce reduced-motion substitutes and class-based utility behaviors.

An IntersectionObserver is needed for ambient UI animations to pause decorative loops when elements scroll off-screen. This mechanism optimizes performance and ensures reduced-motion safe behavior by halting unnecessary rendering cycles for ornaments users cannot see.

Ambient decorative loops like va-orbit and va-rotate should be used for static hero or cover ornamentation, while loading state visuals like va-skeleton and va-pulse are applied to asynchronous content states such as streaming headers and skeletoned layouts to indicate active data fetching.
