The shell around a chat: workspace switcher, new chat, search, thread history grouped by recency with pinned threads on top, and an account menu at the foot. Renaming, pinning, sharing and deleting all work, on demo data you swap for your own backend. Not a generic app shell: everything in it exists for a chat product, and chat-1 is what mounts in the middle. It assumes no router, so it drops into the app you already have.
