Create a clear, 45° top-down isometric miniature 3D educational diorama explaining [PROCESS / CONCEPT]. Use soft refined textures, realistic PBR materials, and gentle lifelike lighting. Build a stepped or layered diorama base showing each stage of the process with subtle arrows or paths. Include tiny stylized figures interacting with each stage (no facial details). Use a clean solid ${background_color} background. At the top-center, display ${process_name} in large bold text, directly beneath it show a short explanation subtitle, and place a minimal symbolic icon below. All text must automatically match the background contrast (white or black).
