     chapter change during continuous scroll. An earlier version animated
     this move with a FLIP transform (GPU-composited, so cheap even
     back-to-back) instead of snapping instantly — technically smooth, but
     on this page it read as the video visibly sliding left/right between
     chapters, most noticeable wherever two alignment flips sit close
     together (e.g. magnification → colour → illumination), which is worse
     than the plain instant snap it replaced. Back to an instant snap; the
     chapter copy's own opacity/transform fade (see .tour__chapter.is-active
     below) carries the "smooth" feel on its own. */
