 * - The sidebar shows a `<TreeSidebar>` (root as a home link + a menu of its children).
 * - `/` renders the root via `<TreePage>`; `/**` catches every deeper path and feeds the full sub-path into `<TreePage>`.
 * - Element rendering uses the default mappings on `<TreePage>`, `<TreeMenu>`, `<TreeCards>`.
 *   Override by wrapping with `<TreePageMapping>`, `<TreeMenuMapping>`, or `<TreeCardMapping>`.
