A dual-layer interactive typography canvas revealing contextual prose beneath a fluid, cursor-driven viewport.

Built around a GPU-composited CSS mask-image layer, a dynamic inline-SVG vector mask, and a coordinates-caching hook that prevents jumping-glitches by letting the mask shrink in-situ on boundary exit. Physics-based easing is handled via a tailored backOut interpolation curve to simulate fluid physical inertia while avoiding main-thread DOM reflows. The result is a seamless, zero-latency reveal effect that maintains a constant 120 FPS.
