Extract a real WebGL / WebGPU / Canvas / shader effect from a live webpage (e.g. an animated
gradient mesh, fluid/metaball, gaussian-splat scene, image distortion) and port it to a
standalone, dependency-light JS project you can run locally or drop into an HTML artifact. Use
when the user points at a site's visual effect and wants to reproduce/port/replay it, especially
complex GPU effects our vanilla recipes don't cover.
