   right over the world, moved by its header and sized from its top and left edges; full screen with one button (a phone is
   always full screen). The Sidebar (the agent's chats and the tools: Search, Projects, Library, Notifications) sits
   beside the chat when the window is wide enough and slides over it when it isn't — at every size. Colours come from the
