A 9:16 clean vertical split screen image, divided horizontally into two equal panels. The scene is THE EXACT SAME, perfectly aligned, ultra-realistic, cinematic photograph of a luxury modern penthouse living room interior at night. Warm glowing fireplace, massive floor-to-ceiling windows showing a blurred soft city lights background, stylish marble coffee table with a steaming coffee cup, designer books, and a glowing tablet. Cozy high-end furniture, rich textures, deep contrast, vibrant warm lighting, edge-to-edge photography with ZERO borders or UI elements. The bottom panel must be the IDENTICAL image with ONLY exactly 3 tiny hidden differences. --ar 9:16
