Create a minimalist book cover design for a professional guide titled "musesai.io". The background should feature a smooth gradient transitioning from deep navy blue at the top to a lighter blue at the bottom, symbolizing progress and clarity. Include an abstract, subtle pattern of interconnected lines or pathways in the background, suggesting the journey through challenges toward solutions. Add a simple illustration of a hand gently holding or reaching for a glowing lightbulb or puzzle piece, symbolizing new ideas and insights. The lightbulb or puzzle piece should be in a warm gold or yellow color, adding a bright contrast against the blue gradient. The overall design should be clean, modern, and professional, with a focus on simplicity and clarity. The style should appeal to business leaders, managers, and professionals looking for practical solutions., 4k --ar 9:16 --v 6.1
