Advanced CSS visual effects: clip-path, masks, backdrop-filter, filters,
blend modes, @property, scroll-driven animations, CSS 3D transforms and Houdini.
USE WHEN: user mentions "clip-path", "backdrop-filter", "mix-blend-mode", "CSS mask", "@property", "scroll-driven animation", "CSS 3D", "Houdini", asks about a visual effect in pure CSS
DO NOT USE FOR: JS-driven animation (use `framer-motion` or `gsap`), SVG-specific work (use `svg-animation`), utility-class styling (use `tailwindcss`)
