Scroll to the bottom. The next statically generated page is appended as its own card, opening with a full-width divider band so where each page begins is explicit. replaceState advances the URL — reload or share and you land on a real page. Without JavaScript, "Load more" is a plain link and the demo degrades to ordinary pagination: the full crumple zone.
