Create a detailed line art mandala featuring a butterfly at the center

Create a detailed line art mandala featuring a butterfly at the center. The mandala should be designed in light, pastel colors, with intricate, symmetrical patterns that radiate outward from the central butterfly. The butterfly should be vividly rendered in orange and black, standing out prominently against the soft, colorful background of the mandala. Ensure the line art is finely detailed, capturing the delicate beauty of both the mandala and the butterfly, creating a visually harmonious and elegant design.
