Molten Ring Carousel

A carousel with no mesh and no image elements: every card is a rounded-box distance field, and one fullscreen pass takes a smooth minimum across all of them. Cards approaching fuse instead of overlapping, and cards separating trail strands that narrow, hang and part on their own, because a strand is another term in the same field. The pointer paints nothing - it widens the fusion radius beneath itself and tips nearby cards toward it.
