2x2 grid, 16:9, do this for unusual classic cars that existed: input ::= [product] step_1 :: infer product physics - weight, rigidity, transparency, reflectivity - how it opens, pours, wears, clicks, or resists - signature silhouette recognisable from twenty feet - the one detail that earns a macro insert step_2 :: infer the single claim - one benefit only: cold, fast, clean, loud, quiet, lasting - the physical metaphor that proves it - what should defy gravity, split, freeze, shatter, or bloom step_3 :: infer world temperature - luxury → negative space, monochrome, deep falloff, stillness - energy → saturation, tilt, motion blur, splash - craft → linen, wood, daylight, hands entering frame - clinical → white cyc, hard edges, zero props step_4 :: infer supporting cast - raw ingredients or components suspended mid-air - surface: wet stone, brushed steel, raw silk, seamless paper - a human element only if it sells the single claim step_5 :: render spec - 100mm, f/8, product sharp front to back - large softbox key plus hard accent for edge definition - flawless surface, controlled reflections, no fingerprints - deliberate empty quadrant reserved for headline copy example_input :: [a matte black espresso tin]
