Create a realistic and visually appealing cover for an online course module titled "Unveiling Real Estate Client Profiles." The cover should feature a high-quality, photo-realistic image that subtly represents the theme within the context of the American Mortgage system and types of real estate clients. Consider using elements such as a modern real estate office environment with real estate professionals (agents, loan officers) engaged in different work activities, client consultations, or a professional networking event for real estate workers. Use a sophisticated color palette that conveys professionalism and opportunity, focusing on dark blue (Navy Blue), white, and gold. The style should be clean, minimalistic, and slightly futuristic. --ar 16:9  --s 750
