Create a colorful and engaging 3D-style book cover for a mathematics textbook with augmented reality features. The main character is a realistic yet friendly-looking capybara standing on all four legs, wearing a captain's hat. The capybara should look intelligent and curious but remain entirely animal-like (no human features or posture). Place the capybara in a high-tech, futuristic classroom filled with educational and digital elements such as floating numbers, geometric shapes, and holographic AR projections. Make the background dynamic and filled with soft light effects to emphasize the augmented reality theme. Leave space for the book title and subtitle. The design should be attractive to middle and high school students — vibrant, imaginative, and educational.
