// #801: статичная фикстура результата оценки для preview-маршрута (a11y/lighthouse).
// Полностью оффлайн — никакой сети. Значения правдоподобны (ЕКБ, 2-к вторичка),
// заполнены ВСЕ surface'ы «денежного экрана»: asking + expected-sold + Avito IMV +
// ДКП-коридор + cian valuation + price_trend + аналоги/сделки.
// photo_url=null у всех лотов — намеренно, чтобы не тянуть внешние картинки
// (чистый оффлайн-рендер для lighthouse/axe).
