Psychedelic Taurus Mandala

Create a square, perfectly centered psychedelic sacred-geometry mandala on a black starfield background. The composition is radially symmetrical with 8 major pointed lotus-petal arms and a kaleidoscopic crystalline structure, glowing like neon stained glass. In the exact center, place a black circular medallion filled with tiny gold stars and draw a delicate golden constellation outline of {argument name="zodiac animal" default="Taurus bull"}. Around it, build a sharp geometric mandala made of many translucent triangular and polygonal facets, with bright thin outlines and small arrow-like markings inside the facets. Use a vivid rainbow progression of {argument name="primary palette" default="electric violet, cobalt blue, emerald green, yellow, orange, and red"}, arranged in mirrored bands so every quadrant repeats precisely. Surround the geometric ring with 8 large dark purple lotus petals containing swirling galaxy spirals in magenta, orange, green, and blue, plus branching lightning-like filaments and star dust. Extend outward into a deep black cosmic background with repeated angular shards, zigzag crystal shapes, and colorful comet-like splinters radiating from the center. The overall mood is mystical, astrological, fractal, and high-energy, with crisp luminous edges, dense micro-detail, glittering particles, high contrast, and no text, border, watermark, or human figures.
