+ * #801: dev/CI-only preview-маршрут «денежного экрана» на статичной фикстуре.
+ *
+ * Зачем: a11y (axe) и lighthouse требуют отрендеренную контентную страницу.
+ * Live trade-in за auth-gate, а локальный фронт без бэкенда = белый экран
+ * (RouteGuard висит на pending /me). Эта страница рендерит реальные компоненты
+ * результата (HeroSummary + карточки/чарты) полностью оффлайн — без сети.
+ *
+ * Включается ТОЛЬКО при NEXT_PUBLIC_ENABLE_PREVIEW=1 (иначе notFound) — в проде
+ * по умолчанию недоступна. RouteGuard пропускает /ui-preview/* под тем же флагом.
+ * (Папка НЕ может начинаться с "_" — Next трактует такие как private/non-routable.)
+ *
+ * Локально:  echo NEXT_PUBLIC_ENABLE_PREVIEW=1 > .env.local && npm run dev
+ *            → http://localhost:3000/ui-preview/estimate
+ * CI:        собрать с флагом, поднять next start, навести axe/lighthouse.
