The WebView is frameless and uses the compact title bar drawn by the interface.
The vehicle rail includes a local STL viewer: choose **Load STL** to show a

The vehicle rail includes a local STL viewer: choose **Load STL** to start with
an orthographic top-view silhouette, then drag to orbit or use the mouse wheel
to zoom. A cached STL copy is stored locally under the ignored `runtime/`
directory so the model can be restored on the next launch.
STEP/STP CAD solids must first be tessellated/exported as STL because the
embedded renderer intentionally does not include a full CAD kernel.
