  "prompt": "Game sprite asset for a realistic top-down planetary exploration game: a small naturally exposed mineral ore deposit emerging flush from soil, STRICT ORTHOGRAPHIC TOP DOWN directly overhead. An irregular broken vein of muted blue-grey metallic ore with a few warm copper mineral seams visible inside jagged earthy rocks. Several substantial partially buried ore fragments, 6 to 10 clearly readable chunks, flat fractured surfaces and natural subdued mineral sheen, surrounded by tiny scattered chips, gravel and a thin loose-soil transition. Make it look like minerals poking out of actual ground, not a collectible crystal, not an icon, not a pile on a platform. No big upright crystal spires. No neon glow, no glitter particles. High fidelity gritty hand-painted 3D game texture style, soft ambient upper-left daylight, shallow baked contact shading immediately under stones. Single compact irregular horizontal oval cluster centered in square canvas, occupies central 65-70 percent of canvas, generous fully transparent margins. True transparent RGBA background. Loose soil and gravel around the edge must disperse naturally into fully transparent pixels, softly feathered alpha, no opaque disc or square of dirt, no hard cutout contour around soil, no backdrop, no outline, no text, no UI. Major stone facets must remain readable when the sprite is reduced to about 100 screen pixels."
