/* ---------- pinned header: rules + title, stuck as ONE block ----------
   The rules banner and the top bar live in the same sticky container on purpose.
   An earlier version fixed the banner and offset the bar by a JS-measured height;
   that measurement ran inside requestAnimationFrame (and later a ResizeObserver),
   neither of which fires while the tab is hidden or backgrounded — so the banner
   covered the title. Sticking them together needs no measurement at all. */
