Mystical atmospheric environment — single cool directional key light from above, deep dark background with subtle environmental depth. The scene atmosphere is esoteric and otherworldly: cool, dark, symbolic. No warm ambient light, no daylight. When no specific material is defined by the font: default lighting environment — cold silver-white overhead key light, deep indigo-to-near-black atmospheric background, faint star field at very low opacity. Cool, ethereal, mystical night atmosphere. Square product photography. A matte black iPhone case flat lay on a white marble surface. Overhead product shot, soft diffused studio light, minimal shadow on one side. Back of the case: SPARKLE printed in Y2K chrome symbol style — liquid chrome letters with integrated 4-pointed sparkle stars, centered on the case back, print approximately 60% of case width. The iridescent chrome and sparkle detail of the print is vivid against the matte black case — electric blue and silver chrome tones catching the studio light. The chrome sparkle print appears slightly raised, premium quality UV print finish. Clean minimal product mockup — white marble background, perfect overhead angle, the case centered in the square frame.
