Layouts

Option	Values	Purpose
layout	stacked, split	Controls form/report arrangement.
reportPane	auto, always, hidden	Controls report pane visibility.

import { predictionTransport } from "./prediction-transport";

mountForm(container, {
  transport: predictionTransport,
  schema,
  layout: { kind: "split" },
  reportPane: "auto",
});

Use stacked for narrow embeds and simple forms. Use split when reports are central to the workflow.
