Card
Gen UI 2.0 standardA bordered panel, only for an interactive panel (controls, a form, a configurator); tables, charts and text need none. Give it a Title and a Caption. Separate groups with a Divider or the gap, never a nested Card or bordered Box. Variant "section": no box; "outline": always a box. In markdown mode, without controls it renders as "section" unless variant or border is set.
One of the 69 components in CopilotKit's standardUI. The playground's catalog extends it, so every agent here can use Card. Standard catalog docs
