Module layout 

Layout system for JSON-UI page rendering.

Provides a trait-based layout system where named layouts wrap rendered component HTML in full page shells. Three built-in layouts are provided: DefaultLayout (minimal), AppLayout (dashboard with nav + sidebar), and AuthLayout (centered card). DashboardLayout is an optional layout that users register themselves with per-app config.

A global LayoutRegistry maps layout names to implementations. Views specify a layout via JsonUiView.layout, and the render pipeline looks it up in the registry.
