 * The opener intro. Figma: 84.29px violet circles on the 1920 artboard, which
 * is 4.39vw. They scatter, then travel into the dot on the end of the lockup.
 *
 * The whole per-dot sequence is driven from scripts/tgc-dots.js through the
 * Web Animations API, so there are no keyframes here to hand over to a
 * transition part-way through. That handoff used to snap: dropping the
 * animation reverted each dot to the rule underneath before the transition
 * picked it up.
