A continuous color-shifting ribbon snakes through the canvas following the user's motion centroid. As the centroid moves, new segments are appended to the head (with a new hue) and old segments fade from the tail after about 3.5 seconds. Rendered as overlapping rounded polyline strokes in two passes — a thick low- alpha outer pass for glow + a thinner bright inner pass — so it has depth without using shadowBlur.
