When a card was clicked, history.pushState changed the URL but left document.title, description, og:*, and canonical pointing at the overview page. navigate() also only updated document.title, not meta. Add setMeta/syncHeadMeta helpers; update title+meta from POSTS data on card open, and sync all head meta from the fetched document in navigate().
