rememberFilamentEngine

Creates and remembers an Engine for the lifetime of the composition.

Each call creates its own engine — hoist one call and pass the value around to share an engine across scenes, views, and loaders (rememberFilamentScene, rememberGltfAsset, rememberKTXEnvironment, …). If you don't pass an engine, rememberFilamentScene and FilamentSceneView create a dedicated one scoped to that call site.
