Como Ganhar Dinheiro pela Internet - Modern Book Cover Design by Jorge Nacano

Create a full book cover (front and back) with a total width of 31 cm and height of 24 cm, including 0.5 cm bleed on all sides. The front cover (right side) should feature a clean, modern design with the title "Como Ganhar Dinheiro pela Internet" in bold, professional lettering, and the author's name "Jorge Nacano" at the bottom. The front should include symbolic elements of online income, such as a glowing laptop, digital coins, Wi-Fi signals, and light coming from a smartphone screen. The background should be dark with golden and blue tech-style highlights. The back cover (left side) should be darker, more minimalist, designed to hold a text block later. Keep it clean, with a soft tech-inspired pattern or subtle digital texture. No text should be included in the image. Maintain high resolution (300 DPI), flat lighting, and realistic styling for professional publishing.
