 * - Splitter (separates panes)
 * - TreeView (left pane navigation)
 * - Breadcrumb (center pane navigation)
 * - ListView or Grid (center pane content)
 * - Preview pane (right pane, optional)
 *
 * Each sub-component implements its own ARIA spec.
 * The only custom rule is that the preview pane must be focusable.
