Declaration

@MainActor class PlaybackRenderer

Summary

Renders each playback frame: (1) draws the recorded camera image as the background, (2) moves the RealityKit camera (pose + FOV) to match the playback frame. PlaybackSession holds an optional reference and calls renderFrame(_:) on the main queue for every new frame. Relation to Apple AR: Manipulates RealityKit—sets arView.environment.background = .color(.clear), adds a PerspectiveCamera and AnchorEntity, and updates their transform and fieldOfViewInDegrees every frame from PlaybackCamera. In playback, ARView's default camera is off; we drive the virtual camera.
