    ## Common Examples

    ### Basic Usage

    Wrap the chat content and any nested `ArtifactPanel` components in `ArtifactPanelLayout`. The layout establishes the positioning context and decides whether each registered panel sits inline or overlays the chat:

    ```tsx theme={null}
    import {
      ArtifactPanel,
      ArtifactPanelLayout,
    } from "@servicetitan/anvil2-ext-atlas";

    function ChatLayout({ messages, panelOpen, setPanelOpen }) {
      return (
        <ArtifactPanelLayout>
          <Content itemsLength={messages.length}>{messages}</Content>
          <ArtifactPanel
            isOpen={panelOpen}
            onOpenChange={setPanelOpen}
            title="Supplemental info"
          >
            {/* artifact content */}
          </ArtifactPanel>
        </ArtifactPanelLayout>
      );
    }
    ```

    ### Responsive Behavior

    The layout observes its own width and decides per-panel whether enough room is available to sit inline alongside the chat. Inline mode kicks in only when the chat content would still have at least 20rem of room; otherwise the panel switches to overlay mode and floats over the chat anchored to the appropriate edge.

    Mode is read from a context internal to `ArtifactPanelLayout` — consumers do not need to compute or pass it. When an `ArtifactPanel` is rendered outside `ArtifactPanelLayout`, it falls back to inline mode.

    ## React Accessibility

    * The layout itself is a presentational `<div>` with no semantics — accessibility is handled by the components nested inside (chat content, `ArtifactPanel` aside landmark, etc.).
    * The layout establishes a positioning context (`position: relative`) so absolutely-positioned overlay panels anchor correctly without consumers needing to wire that up themselves.
