* A focused OSMDroid map composable that renders **only** traceroute visualization — node markers for each hop and

* forward/return offset polylines with auto-centering camera.

*

* Unlike the main `MapView`, this composable does **not** include node clusters, waypoints, location tracking, or any

* map controls. It is designed to be embedded inside `TracerouteMapScreen`'s scaffold.
