 * The track holds the three tags plus a clone of the first. The last step
 * slides to that clone, then the loop restarts at the real first item, which
 * looks identical, so the cycle never visibly rewinds.
 *
 * This animates `top` rather than `transform` on purpose: a transform
 * animation moves the text onto its own compositor layer, which switches it
 * to softer grayscale antialiasing and makes it look blurry mid-animation.
 * The track is tiny, so the layout cost is negligible.
