+[Shot 1] Appearance and scene:
+
+Rendering style of the whole frame: A realistic open coastline in bright maritime light: wet sand, surf-darkened rock, sea spray and a clear horizon, with natural human anatomy, believable scale and detailed physical materials.
+
+The protagonist sits in the driver's seat inside the closed cabin of the racing sedan, entirely within its bodywork, out of sight behind dark reflective glazing, and is never drawn as a separate figure outside the vehicle. The camera-owner racing sedan with a seated driver is a complete graphite-grey racing sedan with a rear wing, featuring doors, windows, and wheels. The AI-driven rival sedan with a seated driver is a complete graphite-grey racing sedan with a rear wing, featuring doors, windows, and wheels. The seated driver of rival racing car 1 sits in the driver's seat inside the closed cabin of the third rival sedan, entirely within its bodywork, out of sight behind dark reflective glazing, and is never drawn as a separate figure outside the vehicle. The seated driver of rival racing car 2 sits in the driver's seat inside the closed cabin of the farther rival sedan, entirely within its bodywork, out of sight behind dark reflective glazing, and is never drawn as a separate figure outside the vehicle. The seated driver of rival racing car 3 is a diver with dark hair under a hood, wearing a charcoal wetsuit with slate panels, the same wetsuit, and fins, seated in the driver's seat of the rival sedan whenever that driver is visible in the reference. Every described entity retains this appearance only while visible in the reference.
+
+The setting is a coastal beach with sloping sand and large shoreline rocks. Preserve the reference spacing, masses and open routes. The player sedan, a complete graphite-grey racing sedan with a seated driver; a complete racing sedan with a seated driver. The camera follows the recorded third-person path of the conditioning reference. Early-morning low sun casts long, soft shadows across the wet sand, with a cool, desaturated colour temperature and a single warm accent hue highlighting the edges of the rocks and vehicles. An asphalt road with white lane markings and low metal roadside barriers runs through the scene exactly where the conditioning reference shows it; keep it a real paved road for the whole clip. Trees stand only where the conditioning reference shows them. There is no box, frame, glass panel, outline or coloured slab around or in front of any person, animal or object in the output; every figure stands directly in the scene.

+The protagonist sits in the driver's seat inside the closed cabin of the racing sedan, entirely within its bodywork, out of sight behind dark reflective glazing, and is never drawn as a separate figure outside the vehicle. The camera-owner racing sedan with a seated driver is a complete graphite-grey racing sedan with a rear wing, featuring doors, windows, and wheels. The AI-driven rival sedan with a seated driver is a complete graphite-grey racing sedan with a rear wing, featuring doors, windows, and wheels. The seated driver of rival racing car 2 sits in the driver's seat inside the closed cabin of the farther rival sedan, entirely within its bodywork, out of sight behind dark reflective glazing, and is never drawn as a separate figure outside the vehicle. Every described entity retains this appearance only while visible in the reference.

+The setting is a coastal beach with sloping sand and large shoreline rocks. Preserve the reference spacing, masses and open routes. The player sedan, a complete graphite-grey racing sedan with a seated driver; a complete racing sedan with a seated driver. The camera follows the recorded third-person path of the conditioning reference. Early-morning low sun casts long, soft shadows across the wet sand, with a cool, desaturated colour temperature and a single warm accent hue highlighting the edges of the rocks and vehicles. An asphalt road with white lane markings and low metal roadside barriers runs through the scene exactly where the conditioning reference shows it; keep it a real paved road for the whole clip. Trees stand only where the conditioning reference shows them. There is no box, frame, glass panel, outline or coloured slab around or in front of any person, animal or object in the output; every figure stands directly in the scene.
