/**
 * The six cones of TxPrismGlow, left to right in the reduced-motion frame.
 *
 * Every timing is a multiple of the component's `duration`: `period` is how long one crossing
 * takes, `breath` one swell, `phase` the start offset. The phase is negative so the flow is
 * already running on the first frame. The periods differ pairwise, so the cones keep catching
 * each other up: merging on the way past, splitting again after.
 *
 * The phases also decide which cones set off together: 2 travels with 6 for the first
 * 0.4 × duration (the whole of a CoreBox search), and 3, 4 and 5 start out together near the
 * right edge and come back in together on the left. On a dark surface overlaps add up towards
 * white, so any two hues merge cleanly. On a light one they blend `normal`, and an overlap is
 * the average of the two colours: hues more than about 120° apart average to grey, which is how
 * blue over yellow read olive-grey. So a light surface trades cone 2's yellow for cone 4's
 * purple, and every group that sets off together stays within 120°. The accent palette spans
 * 100° in all, so it needs no light order.
