Dark Gatorade-Style Portrait

A dramatic, high-contrast studio portrait of a {argument name="subject gender" default="male"} athlete or model in the visual style of a premium sports drink advertisement, centered and facing straight toward the camera in a tight head-and-shoulders crop. The subject has {argument name="hair style" default="short dark hair brushed back"}, visible ears on both sides, and a rugged lower face with a short beard or stubble. Dress him in a dark zip-up athletic jacket with the zipper centered and visible near the collar. Use an almost entirely black background and extremely low-key lighting, with subtle rim light and soft highlights catching the hair, ears, jawline, shoulders, and jacket texture while most facial features remain swallowed by shadow for a mysterious, intense mood. The image should feel monochrome or nearly monochrome, with deep blacks, muted gray highlights, cinematic contrast, gritty texture, and a sleek commercial sports-brand aesthetic reminiscent of a {argument name="brand style" default="Gatorade"} campaign. Vertical composition, minimalist framing, no text, no logo, no props, no visible environment.
