    "prompt": "Bring this still photograph to life with cinematic motion. The young American woman in a flowing white linen sundress stands on a sunlit Pacific Coast cliff at golden hour: her chestnut hair drifts gently in the ocean breeze, the hem of her dress flutters, and she turns her head and breaks into a soft smile as warm sunlight catches her freckles. Behind her, foamy turquoise waves roll and crash against the rocks below, seabirds glide past, and tall coastal grass sways. The camera slowly dollies in from a wide shot to a tender medium close-up, a subtle parallax revealing the depth of the cliffside. Natural ambient sound: gentle Pacific surf, distant gulls, a soft breeze through the grass, faint acoustic guitar in the background. Photoreal skin and fabric textures, hair strand detail, realistic water physics, golden-hour rim lighting, lens flare, shot on Arri Alexa 35, 50mm anamorphic, shallow depth of field, premium cinematic color grade.",
