# Showcase

The flagship XWUISuperApp demo. It walks through the base pattern every `XWUISuper<Domain>` subclass follows, composing a fully navigable shell straight off the base class via `extraTree` / `extraPages` (no subclassing), merging two independent demo apps with the static `merge()` API, and a branded shell with a logo mark, header toolbar slot and notifications badge.

Every shell mounts into its own framed section because an XWUI component clears its container on construct.
