# Showcase

Flagship tour of `XWUIProjectPlanShellPage`, the shared chrome (breadcrumbs, title, the Goals/Grid/Board/Calendar/Charts view strip, a group-by selector and search) every concrete plan page composes. Shows the default chrome, a custom breadcrumb trail with search wired to a live log line, and the group-by selector wired live.

A local `DemoPlanPage` subclass supplies a placeholder content pane, since the shared shell is abstract and real plan pages (grid, board, calendar, charts, goals) each mount their own view.
