The Minimalist's Essence: A Sleek Black Book

Prompt: "Design a vertical, closed black book standing upright. The book should have a sleek black cover with elegant golden borders along the edges, giving it a refined and luxurious look. The cover should be plain with no text or additional graphics, focusing on a minimalist and sophisticated design. The golden edges should subtly catch the light, enhancing the book’s elegant appearance without detracting from its simplicity."
