Transform this empty room into a sophisticated dark minimalist living space. Preserve the original architecture, dimensions, windows, doors, flooring, and camera angle. Use charcoal walls, a deep gray sofa, smoked oak furniture, matte black accents, and a textured dark rug. Balance the dark palette with warm layered lighting, soft curtains, and a few light neutral accents. Adapt the furniture layout to the available space, keeping realistic proportions and clear walkways. Match the original daylight, perspective, shadows, and reflections for a convincing interior photograph. Return only the fully designed room, without text or watermarks.
