Design a captivating coloring book page featuring a central mandala surrounded by an array of geometric patterns. The central mandala should be symmetrical and highly detailed, with intricate, swirling shapes that radiate from the center. Around the mandala, create a border of geometric designs, including interlocking squares, triangles, and hexagons. The lines and shapes should be crisp and well-defined, allowing for easy coloring. Ensure that the overall composition is balanced and harmonious, providing coloring enthusiasts with a meditative and visually pleasing experience. --ar 9:11
