 * Default Streamdown `controls` for assistant markdown (`MessageResponse`).

 * - **Mermaid:** Enables copy, download, and pan/zoom (AX-117, AX-118). Fullscreen is
 *   disabled: it uses a portal to `document.body`, which breaks scoped / prefixed CSS in
 *   micro-frontend hosts until upstream supports a configurable portal root.
 * - **Code / table:** Off so chat keeps a simpler surface; callers may override via the
 *   `controls` prop on `MessageResponse`.
