 Details payloads are cached in browser `localStorage` for five minutes per object path. When you reselect an object, cached properties render immediately and the app refreshes them from Unreal in the background.
 
+Asset-looking property values also request `/remote/object/thumbnail` and cache thumbnail data in `localStorage`, so mesh/material fields can render closer to Unreal's Details panel.
+
 ## Run
 
 Start Unreal Editor, enable the Remote Control API, and make sure it is listening on `127.0.0.1:30010`.
