// DashboardPage reads the shared getting-started path (#396). No jsdom:
// react-dom/server renders in vitest's node environment. The path comes from a
// fake `useOnboarding()`, and the dashboard's data hook and widgets are stubbed
// to markers: what is pinned is the page's branching on the path. Since #397
// the page has no list of its own once transactions exist: the banner of
// AppShell replaced the compact bar (D7).
