+// /trade-in/v2 — "МЕРА Оценка" HUD dashboard, wired to the real trade-in API.
+// This page OWNS the data: it runs the estimate mutation + restore-by-id query,
+// spawns the dashboard sub-hooks (street deals, house analytics) and feeds the
+// pixel-perfect HUD components via the pure mappers (mapReport / mapObject /
+// mapResultPanel / mapSummary). The artboard frame / brackets / 474-1fr-250 grid
+// are unchanged — only the result/summary areas swap between honest empty / grey
+// skeleton / inline-error / real-data states. Sub-hooks resolve independently:
+// a pending or errored street-deals / analytics call degrades its section to a
+// fallback inside the mapper instead of blanking the page.
