/* ---- motion ---------------------------------------------------------------
   Three moves, each for a reason: the hero enters in reading order (the claim,
   then the readings behind it), buttons give under a press, and .reveal blocks
   settle in as they scroll into view so a timeline reads in sequence. All of it
   is off for anyone who asked for reduced motion. */
