Generate a low-res webcam collage of late-night moods

Create a vertical 3-frame low-res webcam collage. The image must have dim late-night screen lighting, a grainy and noisy webcam texture, and a simple bedroom background. Each of the three frames should show a different casual, expressive late-night mood (like tired, playful, or smiling). Maintain consistent subject identity, messy hair, and natural webcam framing. High fidelity to the original photo.
