One formal Game/Scene combines streamed collision cells, real physics sweeps and navigation goals, retained UI, resource churn, native silent audio, pause, durable save/restore, crossfade and same-backend graphics recovery before continued gameplay. Canvas2D runs the 2D variant; 3D and native graphics recovery are explicitly unavailable.

VRAM certification.
