* the client never does staleness math): a rose "Stale" pill when
* the row was saved before the last KB-changing sync, an em-dash

* chat-page banner (task 05); opening the row is the action;
* • Share — phase 51 (owner-locked 2026-08-29, TODO.md L6): the
* row's share state, rendered from the list's OWN share_url (the
* GET /api/chats endpoint populates it — no second fetch per row).
