# Ghost Reveal

> A soft, feathered image reveal for React. Instead of a fade or a hard wipe, a tall cloudy alpha mask slides across the element via animated mask-position, so content bleeds in through a ghostly, feathered edge — like the image is forming out of fog. Zero dependencies (React only). Scroll-triggered once via IntersectionObserver by default, or drive it yourself with a controlled `play` prop. Reveals from any direction (up, down, left, right) using vertical and horizontal feather masks with no element rotation (so nothing clips), tunable softness (scale/mask-size), duration and CSS easing, an onHidden callback for swapping the child exactly when nothing is visible, and a graceful opacity fallback under prefers-reduced-motion.
