// Vitest coverage for the Phase 22 races table active view. The
// component renders against a synthetic `RenderedReportSource` (no
// live `GameStateStore`) and a real `OrderDraftStore` (so the per-row
// stance toggle and the vote picker exercise the `add` path and the
// IndexedDB persistence end-to-end). The render path also flows
// through `applyOrderOverlay`, so the optimistic flips made by the
// component must keep the test fixture's report intact: each test
// passes the *raw* report and the helper recomputes the overlay on
// every snapshot.
