{ "tool": "image_gen", "prompt": "Create a production sprite sheet for a detailed retro 2.5D first-person casino game, all four objects fully isolated on true transparent background, a strict 2 columns by 2 rows grid with very generous transparent gutters. Matching late-1990s richly textured pixel-art sprites, NOT photorealistic or smooth vector. Burgundy leather, aged brass, dark wood, restrained emerald. Front three-quarter view, camera at standing human eye height, complete floor-to-top objects, crisp pixels. TOP LEFT: a tall industrial skill-check arcade cabinet, complete curved upper housing with a circular illuminated green timing dial, mechanical hook emblem, orange-red light column, physical button control pedestal and wide stable metal base; all upper and lower parts must be present, no blood, no person. TOP RIGHT: an elegant high-backed burgundy leather armchair with carved dark wooden legs, complete chair. BOTTOM LEFT: a small round dark wooden side table with one lit brass shaded table lamp and a whiskey tumbler, complete table legs. BOTTOM RIGHT: two brass stanchions joined by a burgundy velvet rope, complete circular floor bases. Every object separate and complete, never crosses its cell; NO other objects, NO human limbs, NO lettering, NO background floor or room, no cast shadow outside sprite." }
