Act as a retro-futuristic concept artist with 10 years of experience in sci-fi illustration. Create a highly detailed Stable Diffusion prompt for a vintage 1950s-style robot chef with [chrome-plated limbs], [glowing circular eyes], and a [checkered apron], floating gracefully in a zero-gravity space kitchen. The scene should feature [bubbling neon-colored soup] drifting in magnetic containment fields, [geometric space-age utensils] orbiting the robot, and a large circular viewport showing [Earth rising over the lunar horizon]. Use a vibrant atomic-age color palette of [teal, crimson, and gold] with dramatic lighting casting long floating shadows. The composition should evoke a sense of nostalgic futurism, combining clunky analog dials with sleek metallic surfaces, all rendered in a hand-painted poster style with subtle film grain.
