Create a high-quality, photo-realistic cover for an online course module on 'Mortgage Process Overview.' The image should feature a professional, modern office environment with real people engaged in various stages of the mortgage process. This could include a mortgage officer reviewing documents, clients discussing loan terms, or professionals working with financial data on computers. Include visual cues like property blueprints, loan documents, real estate images, and professional tools, all representing the phases of the mortgage journey--application, underwriting, document verification, appraisal, and approval. The color palette should focus on deep navy blue, gold, and white tones, ensuring the image feels sophisticated, trustworthy, and professional. No text should be included in the image. --ar 16:9  --s 750
