Vertical 9:16, photorealistic, cinematic lighting, modern office desk, shallow depth of field, high contrast, realistic textures, soft shadows, professional commercial photography, 4K, sharp focus, slight background blur, no people, no hands, no text, no logo, no watermark. Night desk mood: messy papers and sticky notes, laptop with a blank slide placeholder (no text), coffee cup, analog clock (no readable numbers), “work dragging on” feeling.
