The top of every page is one surface: the breadcrumb, search, spend, Ask g1t, bell and + share one height, corners and spacing, Ask g1t is a plain tinted button with the g1t mark drawn on whole pixels, a page's own header sits directly under the bar at the same left edge, and every section, conversations and open artifacts included, draws the same rounded panel. Tables written in chat render as tables, and the site's file, checkbox, radio, number and date controls are the design system's. Button, Separator, Breadcrumb, Table and FileDrop join the shared components; the chat guide says how tables work.74 "| Session | Length |\n| --- | --: |\n| **Welcome** | `45` min |",
