/* ============================================================
   HOMEPAGE — art first
   Three full-height art panels for the three games, then one
   section per game with the artwork leading and a few lines of
   copy. Motion: one entrance on load, slow scroll reveals, and a
   gentle scroll-linked drift on the art where the browser supports
   it. Builds on style.css (Cinzel + Karla, ocean background, gold).
