1/**
2 * Fresh-content hydration for the header news ticker and the homepage
3 * "most read" block.
4 *
5 * Both are server-rendered into the (Cloudflare / Super Page Cache) edge-cached
6 * HTML, so a page cached for the whole HTML TTL would otherwise show stale
7 * headlines until the object expires. This swaps in a fresh fragment on load
8 * and on a slow interval / tab focus, and re-runs the fragment's inline scripts
9 * so widget bindings (jNewsbar ticker, "show more headlines") keep working.
10 * External <script src> tags are left alone: the libraries are already loaded.
