Create a 15-second realistic cinematic video of a woman skateboarding fast down a steep coastal hill road toward the ocean. Open with a dynamic rear chase angle from slightly above and behind her capturing the dramatic downhill slope and expansive ocean view ahead. The environment is a bright, sunny seaside town with narrow roads, stone walls, utility poles, small houses, rooftops, side streets, and lush green hills leading down to a vivid turquoise-blue coastline with large waves and towering white clouds. The woman has long black hair, soft natural facial features, warm light-medium skin, and a slim youthful build. Dress her in a stylish casual coastal outfit: an oversized blue shirt, denim pants, white sneakers, and a small slingbag. Her hair and clothing move naturally in the wind as she rides. She is skateboarding continuously and quickly downhill, carving gently and smoothly with believable balance and natural physics. The motion should feel exciting, free, and grounded in reality. Add a small number of cars on the road to make the scene feel alive - only a few, not heavy traffic. Include perhaps one car driving farther ahead in her lane, one parked vehicle near the roadside, and one occasional passing or oncoming car at a safe distance. The vehicles should feel natural and integrated into the town, adding realism and motion without becoming the focus. The road should still feel mostly open so the skateboarder remains the clear subject. Use realistic lighting, natural motion blur, subtle camera shake, and an immersive handheld/chase-camera feel. Keep the entire scene fully photorealistic, not animated or illustrated. For most of the video, keep the camera behind her as she rides fast downhill with the ocean stretching out in front of her. In the final few seconds, the camera glides from behind to the side and then arcs around to the front, revealing her face clearly while she is still riding. She looks calm, focused, and slightly smiling, enjoying the ride. End on the face reveal while she continues moving downhill. Audio: no background music. Ambient sound only - skateboard wheels rolling on pavement, wind, distant ocean, and light neighborhood traffic sounds.
