    "prompt": "Cinematic multi-shot of a young American couple celebrating their anniversary at a candlelit terrace dinner in Tuscany at golden hour. Wide establishing shot sweeps over rolling vineyard hills, cypress trees casting long shadows, then cuts to a slow dolly-in on a stone terrace where a woman in an ivory linen dress laughs softly while the man in a navy rolled-sleeve shirt pours red wine. Cut to a tender close-up: their hands interlace across the table, candlelight catching her diamond ring, his thumb gently brushing hers. Cut to a profile two-shot as he leans in and whispers; she smiles, eyes glistening, golden light rim-lighting her loose blonde hair. Final shot: a graceful crane pull-back revealing the terrace, the warm villa, and the sun melting into the Tuscan horizon. Distant church bells, light cricket ambience, soft acoustic guitar. Photoreal skin, fabric texture, wine ripples — shot on Arri Alexa 35, anamorphic lenses, shallow depth of field, premium cinematic color grade."
