Wrap every `NavItem` in `PageShell.RailPeek` and compose its panel with `PageShell.PeekHeader` / `PeekFacts` / `PeekLinks`. Search is a button row opening `CommandMenu` (⌘K); settings' peek holds the quick controls; phones get `PageShell.MobileTabBar` (≤ 5). No `TopBar` in an app frame. Opt-ins only when a product needs them: the labelled panel (`sidebarMode=\"auto\"`, ⌘\\\\ collapse, ADR-040), `island`/`column` (ADR-025), the bubble (`mobileNav=\"bubble\"`)"
