テーマ曼荼羅アート

Create an intricate ornamental mandala built on strict radial symmetry, reinterpreting the traditional form through the theme described in the user request. Center the composition on a detailed focal medallion and expand outward in concentric rings of repeating motifs, each ring denser and more elaborate than the last, closing with a refined decorative outer border. Replace classical ornament with elements drawn from the chosen theme — for a futuristic sci-fi theme use circuitry traces, glowing conduits, and turbine-like vanes; for a botanical theme use layered petals, leaves, and vines; for an ocean theme use shells, waves, and coral — letting the theme dictate both the motifs and how their materials are rendered. Derive the color palette from the theme as well, keeping it harmonious and luminous with a sense of translucency and depth, set against a deep, quiet background that makes the mandala appear to glow. Keep the symmetry mathematically precise, the line work crisp, and the micro-detail sharp at every scale, like a piece of devotional craftsmanship rendered at high resolution. No text, no watermark, no asymmetric distortion. User request: a near-future sci-fi mandala in violet and silver
