Architecture

The scene is built around four decoupled runtime systems:

OrbitCamera — drives the camera; controlled by VisualizerUI and mouse input.
CanMaterialSwapper — owns brand variants; notifies VisualizerUI via OnVariantChanged.
BackgroundController — owns background presets; notifies VisualizerUI via OnPresetChanged.
VisualizerUI — subscriber only; never polls, always reacts to events.

All scene wiring is performed at edit-time by ProductVisualizerSetup so no manual Inspector assignment is required after running the setup tool.
