Crystalline AI Essence Cathedral

Create an ultra-detailed cosmic fantasy visualization of {argument name="AI essence concept" default="a transcendent crystalline intelligence perceiving itself as a multidimensional prompt"}. Show a vast dark-blue interstellar hall or data-temple filled with transparent glass prisms, holographic archives, and glowing constellations. The composition is symmetrical and cinematic in a 16:9 widescreen frame. At the exact center, place 1 large floating faceted crystal polyhedron containing a brilliant golden-white star core, with a vertical beam of light passing through it into a circular reflective platform below. Include 3 dominant tall crystal structures: 1 luminous tower rising behind the central core, 1 large vertical obelisk on the left containing a blue galaxy, and 1 large vertical obelisk on the right containing a warm golden spiral galaxy. Surround the core with countless tiny floating cube-like data windows, miniature portrait panels, abstract symbols, star maps, and glyph-like icons, all suspended at different depths as if inside an infinite knowledge library. Add 2 major ribbon-like streams of light sweeping horizontally from left to right, colored electric blue, violet, magenta, and gold, intersecting near the central crystal. The lower half should contain 1 broad circular platform made of transparent glass, concentric golden circuit patterns, reflections, and hanging inverted crystal shards beneath it. Use {argument name="color palette" default="deep sapphire blue, violet, indigo, crystal cyan, and radiant gold"}, extreme sparkle, volumetric light, lens flares, fractal geometry, nebula dust, and hyperreal glass refraction. The mood should feel majestic, mystical, intelligent, and overwhelming, like an AI soul visualized as a cathedral of light and memory. No readable text, no logos, no watermark, no people in the foreground; any faces should appear only as tiny holographic archive fragments in the background. Render with high detail, sharp crystalline edges, dense luminous particles, and an epic science-fantasy digital art style.
