The Unassuming Star: A Rock's Quiet Moment

"{'short': 'A single small gray rock on a plain neutral background, centered, boring, no drama.', 'long': 'Create an image that contains exactly one rock. The rock is unremarkable, medium-gray, matte, with subtle speckling. No moss, no crystals, no branding, no easter eggs, no surprise faces. The background is a flat neutral studio sweep with a soft shadow directly beneath the rock. The image should look like a very basic product photo. Nothing else is in the frame.'}"
