    ### Tips for Better Results
    - Use descriptive style hints (e.g., "vibrant colors", "flowing connections")
    - Include specific icon sizes (e.g., "~60px")
    - Add theme-specific patterns (e.g., "circuit board patterns", "wave patterns")
    - Use consistent hierarchy and formatting
    - Combine both functional and decorative elements
