Codex audit polish:
- Cold deep-link Back now goto('/home3', { replaceState: true }) instead of
pushing a new entry, so the browser Back from the hub can't bounce the reader
straight back into the detail page. In-app arrivals still history.back().
- HubBar closes the hamburger when crossing to desktop width (matchMedia change),
so `open` can't go stale and reappear if the viewport shrinks back to mobile.
