   REVEAL: add [data-reveal] (optional ="start|end|zoom", style="--i:N" delay step) or [data-reveal-group]
   (children stagger). JS adds .is-visible via IntersectionObserver. Without "js" class everything is visible.
   PRIMARY CTA: always class="btn btn--primary" + data-cta="primary" href="game.php" (no JS handlers).
   Utilities: .container .visually-hidden .stack .text-center [hidden]
