The centerpiece is the watch showcase — a scroll-driven 3D assembly of the flagship "Calibre One" automatic. As you scroll, all 8 components (case, movement with visible gearing, dial, markers, hands, bezel, sapphire dome, crown + straps) float in from space and assemble themselves piece by piece in real time, with staged captions explaining each part and bronze particle effects tying it together. Built in Three.js/React Three Fiber, with a WebGL fallback so it degrades gracefully on older devices.
