# Iridescent Foil

> A holographic foil surface built entirely from layered CSS gradients — a base foil, a soft color film, a pearl sheen, a directional shine, and a specular glare, blended with mix-blend modes. Moving the pointer over the element (or scrolling the page) shifts the iridescent color and specular highlight across the surface via requestAnimationFrame-driven CSS custom properties. Wrap any content as children; element or document scroll-progress modes; dependency-free (ships a CSS module).
