Cinematic Forest Runner

Create a cinematic widescreen film still of {argument name="character" default="a young person with short black hair"} running away from the camera through a quiet forest. The subject is centered slightly left, seen from behind, mid-stride, with one bare arm bent and visible, wearing a flowing {argument name="outfit" default="sleeveless translucent white dress or robe"} that trails dramatically to the right like a soft veil caught by motion. The forest contains tall, straight tree trunks receding into depth, dense green undergrowth, and a faint dirt path on the left foreground. Use cool teal-green color grading, early morning mist, soft diffused natural light, shallow depth of field, gentle motion blur on the fabric and background, and an emotional dreamlike music-video atmosphere. Compose in a 2.39:1 cinematic aspect ratio, low-to-mid camera height following behind the runner, with realistic photography, soft focus edges, no text, no logos, no extra people.
