Particle Field Hannya Mask

Scroll-driven Three.js particle scene in a single HTML file: one THREE.Points cloud of 6,000 mint points samples a 3D Hannya mask, dollies in from deep space, then dissolves outward at the end of the page. A CPU solver punches a circular hole that follows the cursor, a procedural sprite shader fakes bokeh without post-processing, and lil-gui swaps silhouettes (star, SVG bolt, ring). Uses Lenis smooth scroll, an SVG fallback and a lighter mobile particle budget.
