    "prompt": "Native-4K cinematic multi-shot of a Brooklyn artisan coffee shop on a rainy autumn morning. Wide establishing shot through a fogged-up window: a bearded American barista in a denim apron stands behind a polished copper espresso machine, brass fixtures glowing under warm Edison bulbs, exposed brick and hanging plants in the background. Cut to an extreme macro close-up of milk being steamed, micro-foam swirling with visible bubbles and droplets. Cut to a top-down macro shot of his hands pouring a perfect rosetta latte art into a matte ceramic cup, golden crema rippling in slow motion. Cut to a young woman in a cream cable-knit sweater receiving the cup, soft window light catching freckles on her cheeks, green eyes warming as she smiles. Final shot: a slow dolly-out reveals the cozy industrial interior — vinyl records spinning, a chalkboard menu, raindrops streaking the window. Sound of espresso machine hissing, gentle rain on glass, soft indie acoustic guitar. Hyper-detailed textures: yarn weave, hair strands, crema bubbles, raindrop refraction — shot on RED Komodo 6K, anamorphic lenses, shallow depth of field, Kodak Portra color science."
