The server-rendered /a/ summary page had no in-page way back — the only option was the browser's back button, which feels unfinished. Add a "← Back" control on the right of the top bar (desktop + mobile). It uses history.back() when the reader came from within the site, and falls back to the home page for visitors who arrived via a shared link (no useful history).
