## Notes
- The API operates on **the currently open scene** in 3ds Max. Open the target scene before calling.
- Write operations (add / remove / replace, etc.) directly modify the scene. Save the scene file manually to keep changes.
- All public API write operations run in **automatic silent mode**. No confirmation dialogs are shown.
- To synchronize the display after API operations while Fast Ref UI is open, call `api.update_ui()`.
