Expand based on the original storyboard script. For every shot, **the duration, shot size, and camera movement must be fully preserved without modification**. Only expand: environmental lighting and shadows, object materials, subtle facial expressions, muscle movement details, ground environment, air atmosphere, and camera parameters. Actions must conform to realistic physical logic; the art style must remain consistent throughout; all character features from the reference images must be fully preserved; modifying facial features or outfits is prohibited. Output detailed storyboard copy segmented by time, ready to be directly imported into AI video tools.
