4K Ultra HD, medium shot, photorealistic cinematography, hyper-detailed, sharp focus. The frame is bright and transparent with vivid, saturated colors and crystal-clear image quality. A white steamed bun is centered in the frame, placed on a matte black stone plate; a human hand with natural skin texture gently grabs the steamed bun and slowly tears it into two halves, with the tearing motion smooth and natural. Instantly cut to an extreme close-up of the steamed bun’s cross-section, capturing the soft, porous, and fluffy texture of the bun’s crumb in sharp detail— every tiny air pocket and delicate wheat fiber is visible. The background is a dark-toned wooden kitchen cabinet with a matte finish, intentionally darkened and heavily blurred (bokeh effect) to create a strong contrast with the bright white steamed bun; soft key light from the front highlights the steamed bun’s texture while keeping the background in deep shadow.
