 * E2E: contextual sidebar companion model.
 *
 * Most contextual routes render their navigation beside the stable global
 * sidebar. Settings intentionally takes over that sidebar while preserving the
 * account menu, and its Back to app link restores the global navigation.
 *
 * Plugin route sidebars share the same Layout path. A live plugin-route test
 * requires a plugin fixture, so that branch remains covered by Layout tests.
