Create a cinematic vertical sports victory poster featuring {argument name="subject" default="a male soccer champion"} as a full-body figure standing triumphantly on top of a gigantic glowing soccer ball at the center of a futuristic packed stadium. The subject wears a black soccer kit with gold trim, black shorts, black knee socks, and gold cleats, posed confidently with one foot on the ball and one arm raised high holding the golden FIFA World Cup trophy. Use dramatic rain, wet reflective ground, blue-gray storm clouds, heavy stadium floodlights, mist, and a heroic low-angle perspective. The oversized soccer ball should dominate the lower foreground, with black and metallic gray panels separated by bright golden glowing seams and a warm reflection on the rain-soaked floor. In the background, show a massive cheering crowd and exactly 2 large blue digital stadium screens, one on the left and one on the right, both displaying the bold text {argument name="screen text" default="WORLD CHAMPION 2026"}. Also include repeated ribbon-board text around the stadium reading the same championship phrase. In the sky above the athlete, include exactly 4 major firework bursts: one smaller gold burst on the upper left, one blue burst near upper center-left, one large bright blue-white burst at upper center-right, and one gold burst on the upper right, with additional thin spark trails but no extra main bursts. Style the image as ultra-realistic, high-contrast, glossy, cinematic advertising photography with volumetric light beams, water droplets, lens flare, and epic World Cup celebration energy. Keep the composition centered and symmetrical, portrait aspect ratio 9:16, no watermark, no logos beyond subtle kit-style emblems, and make all text legible.
