// Vitest coverage for the Phase 17 ship-classes table active view.
// The component renders against a synthetic `RenderedReportSource`
// (so the suite does not need a live `GameStateStore`) and a real
// `OrderDraftStore` (so the per-row Delete affordance exercises
// the `removeShipClass` add path including persistence).
