Create a jubilant football-tournament poster set in a deep midnight stadium atmosphere. Center the exact text "13" as the undisputed hero, enormously scaled and arranged on one line with a slim, even gap between the two characters. Keep a generous field of dark negative space around it so the flags within the text remain instantly readable. Behind the text, show a softly defocused football pitch receding toward a distant goal, its emerald turf marked by barely visible pale field lines and illuminated by low stadium floodlights. The lighting should remain restrained: a cool blue-black sky and shadowy spectator stands create contrast, while a subtle pitch-green halo sits only in the surrounding air and turf. Place a few tiny, out-of-focus black-and-white footballs near the far touchline and one faint corner flag at the edge of frame, never overlapping the text. Fine gold confetti flecks drift sparsely through the background, concentrated near the upper corners and kept clear of the lettering. The composition is clean, celebratory, premium, and sporty, with soft atmospheric haze behind the central text and crisp foreground focus reserved exclusively for "13".
