Use the first uploaded image as the locked master reference.
This is a screen replacement task, not a scene generation task.
Keep the entire image unchanged: preserve the exact monitor, bezel, screen perspective, reflections, lighting, colors, desk, environment and composition.
Replace only the content displayed on the monitor screen.
Use the second uploaded image as the exact reference for the new screen content. Place it inside the monitor display area, perfectly fitting the existing screen boundaries and perspective.
Make the replacement look like a real computer display: realistic brightness, contrast, subtle reflections and natural integration with the original lighting.
Do not change the monitor shape, angle, size or position. Do not alter anything outside the screen area. Do not add new objects. Do not recreate or redesign the interface.
Only replace the existing screen content with the provided reference image.
