Sierpinski (perf stress)
6,500+ motion.divs subscribing to one shared MotionValue via style — the canonical fan-out stress test, with live FPS counter and depth slider.
Every dot is a <motion.div layout> inside a <LayoutGroup dependency={shuffleTick}>. A timer Fisher-Yates shuffles the dot-to-slot mapping every 2.5 s and bumps the dependency; the broadcast re-fires every descendant's measurement and each dot FLIPs from its old slot to its new one. Layered on top of the original stress demo's per-dot scale-pulse (shared MotionValue) and seconds-counter (Solid fine-grained text reactivity).
