How it works
Custom ShaderMaterial; pointer is smoothed with Vector2.lerp and passed as a uniform.
Cursor-Reactive Shader Blob
An icosphere whose vertices ripple outward from the cursor, with a normal-based palette.

Performance
Renders through the single shared <Canvas> via drei <View> — no extra WebGL context, and the render loop only runs while a view is mounted. Playground writes straight into uniforms.value — zero React renders while dragging a slider.
Accessibility & reduced motion
In reduced mode the scene renders on demand only: a static, fully lit frame with no idle motion.
