Cloning needs a Chromium-based browser (WebCodecs media streams).

Segments the person out of the webcam (via longpipe) and composites them in front of the visualizer. Mix = opacity, Mirror flips the overlay. "Show matte" previews the segmentation mask. "Clones" duplicates the subject along a line (Direction sets the angle, Spacing the density, auto-fit keeps them on-screen). Blend and Kaleidoscope apply to the raw (non-isolated) overlay only.
