Releases pages unified with home feed header
The releases pages now use the same header components as the home feed, eliminating custom header code and creating a consistent look across the site.
The releases pages at /releases/ and /releases/page/[n]/ previously had their own custom header markup that differed visually from the home feed. Now both pages use the shared FeedHeader and SectionNav components already powering the Latest tab.
Developers had been maintaining duplicate header code across three pages. That duplication is now gone — the publicationSubtitle field was added to power the shared component on releases pages. The navigation bar chip for "Releases" is automatically highlighted based on the current URL path, just like it works on the home feed.
Site visitors get a consistent experience whether they're browsing the latest posts or historical releases. The empty state ("No editions yet") also receives the shared header treatment, so the page feels complete even without content.
