Design a detailed mandala for a coloring book page. The mandala should feature a central lotus flower, surrounded by multiple layers of intricate geometric patterns. Each layer should differ in design, incorporating elements such as spirals, diamonds, and delicate lace-like details. The outermost layer should resemble a sunburst pattern, adding a dynamic edge to the overall design. Integrate subtle floral motifs and tiny leaves throughout the geometric patterns for organic contrast. The design should be symmetrical and radiate from the center, suitable for meditation and relaxation. Use a bold, clean line style to ensure that each detail is clear and enhances the therapeutic coloring experience --ar 17:23 --s 750 --niji 6
