Both sides play the same live HLS stream with hls.js, as production does, and draw TGI's real augmentation for this game without reading the video's pixels (as under DRM). Left: how OTT-Web schedules the draw today (a message to the worker on each video frame callback, drawn when it arrives, plus its fixed +2 frame correction). Right: the worker's own animation frames, a media clock that predicts the frame for each refresh, and the video composited with the page. Watch the ads during camera pans. Measured numbers: docs/OLD_VS_NEW.md.
