// Phase 8 closure for TEST-M1 — full-flow happy-path tests at the
// Vitest layer using MemoryRouter for 2-3-page navigation. These are
// cheap relative to Playwright (no real browser, no webServer startup
// cost — ~200ms each) and catch the dominant regression class for
// route-level + cross-page-state bugs that per-page tests miss by
// construction.
//
// Why this layer matters:
//   • Per-page tests mount one page in isolation. They miss "click on
//     a row in page A navigates to page B which loads data X".
//   • Playwright catches everything but at 5-second startup cost per
//     run. Reserving Playwright for the 5 priority customer flows
//     (Phase 8 TEST-H1) keeps CI runtime sane.
//   • Vitest MemoryRouter flows hit the React Router + TanStack Query
//     wiring that pure unit tests skip. If a route's `enabled:` gate
//     or a queryKey shape regresses, this layer screams.
//
// Mocking posture: same as the per-page tests — vi.mock the api/client
// module and resolve fixtures synchronously. The flows differ from
// per-page tests in WHAT they assert (cross-page transitions + data
// continuity) not in HOW they mock.
