 A minimal read-only browser consumer can render the sections directly:
 
 ```js
-const view = window.linuxCncIniPanelApi.getMachineSessionControlView();
-for (const section of view.sections) {
-  renderSection(section.title, section.rows);
-}
+window.linuxCncIniPanelApi.renderMachineSessionControlView(
+  document.getElementById("machine-session-control-view"),
+);
 ```
 
 Consumers should treat `rows` as display data and keep actions wired through
 explicit workflow APIs instead of deriving behavior from labels.
 
+For external pages that only have a view object, import the pure renderer:
+
+```js
+import { renderMachineSessionControlView } from "./control-view-renderer.js";
+
+renderMachineSessionControlView(container, view);
