/*
 * Integration Beam – an animated product scene, in a single self-contained file.
 * Your product sits in the middle, three tools on each side, joined by curved beams. In sync cycles,
 * soft light pulses travel from the tools on the left into the product and on out to the tools on the
 * right; every arrival makes the target glow. Hover a tool to bring its beam forward, click it to
 * pause it. The beams are measured from the real tile positions, so the scene reflows with its
 * container – on narrow widths the tools stack above and below and the curves morph into place.
