+// TIRREDESIGN-10 — Onlineboard list rows must surface "Купить билет"
+// and "Онлайн регистрация" inside the expanded body when the per-flight
+// visibility rules pass:
+//   • Buy: now ∈ [departure - buyTicketMaxHours, departure - buyTicketMinHours]
+//   • Register: leg.transition.registration.status === "InProgress"
+//
+// We use a route view loaded via a synthetic fetch hook would be brittle,
+// so this spec drives the live API via /onlineboard/route/MOW-LED-<today>
+// and walks the rendered list to find a Запланирован row whose departure
+// is far enough in the future to clear the buy window. If no such row
+// exists (e.g. late evening when no scheduled flights remain), the test
+// is skipped — it cannot assert against an empty board.
