Exclude any form of shadows or shading in the scene, whether from natural or artificial light sources. Avoid the use of gradients or subtle lighting effects that suggest depth or dimension. Ensure that all cut walls are filled with a solid, uniform dark color without textures, highlights, or additional details that break the flat appearance. Do not include reflections, soft light transitions, or any element that disrupts a clean, diagrammatic representation of the architectural cut.
