Guide Claude on creating Vaadin 25 views with @Route, setting up router layouts (AppLayout, @Layout), navigation between views, and passing data via URL parameters. This skill should be used when the user asks to "create a view", "add a route", "use @Route", "set up navigation", "use AppLayout", "build a navigation menu", "use SideNav", "pass data between views", "use route parameters", "use query parameters", "create a master-detail view", "use @Layout", "use RouterLayout", "use @ParentLayout", "use @RoutePrefix", "use @Menu", "use RouterLink", or "navigate programmatically". Also trigger when the user needs help choosing between route parameters and query parameters, building a MainLayout with a drawer and navigation menu, or structuring nested router layouts.
