/* Nothing waiting to reveal anchors the scroll. Chrome puts a page the

   they left it by finding the element that was at the top of the view
   and restoring its offset – and an AOS element that has not played yet
   sits 100px from its place, so a page came back 100px further down than
   it was left (Charlie, 2026-10-29, found on The Hall School). Out of the
   running, an element that does not move anchors instead, and the page
   comes back exactly where it was left. */
