Create a dramatic vertical football club signing announcement poster in a hyper-realistic sports marketing style, 4:5 portrait composition, dominated by intense red and dark green lighting. Center a young Black male footballer from chest-up, standing straight and facing forward, wearing a half-red half-dark-green jersey with subtle camouflage texture, gold trim details, a small gold manufacturer mark on the right chest, and the Canon Sportif de Yaounde crest on the left chest. The player’s face is intentionally obscured by a large soft-edged rectangular blur block, while his ears, neck, hairline, and jersey remain sharply visible. Behind him, place a large Canon Sportif de Yaounde shield logo on the upper left with exactly 4 gold stars above it, and a smaller club crest centered near the top. Across the very top, add spaced uppercase white text reading COMMANDEUR DE L'ORDRE DE LA VALEUR. Build a fiery textured red background with smoke, glowing particles, layered stadium atmosphere, and a faint old cannon illustration on the upper right. On the mid-right background, add translucent text reading "SINCE 1930". Over the player’s torso, create the main headline typography in 4 stacked text lines: a gold handwritten script first name Christian, a huge distressed white surname KOFANE, a smaller white uppercase line "SIGNE AU", and a massive bold red uppercase line "CANON", followed by a smaller white uppercase line "SPORTIF DE YAOUNDE". At the bottom foreground, show exactly 3 supporting objects: 1 folded club jersey on the lower left corner, 1 football with club branding on the lower right corner, and 1 printed contract document centered near the bottom on a wooden table with a black-and-gold pen resting diagonally across it; the visible contract title should read "CONTRAT DE PERFORMANCE" and the signature area should show Kofanee. Add a row of exactly 4 small social media icons on the bottom left followed by the handle @CANONSPORTIFOFFICIEL. Along the very bottom center, add spaced uppercase white text reading "UN NOUVEAU CHAPITRE COMMENCE" with a small "1930" beneath it. Use cinematic contrast, glossy sports-poster retouching, sharp jersey fabric detail, dramatic rim light, bold editorial typography, and elite African football club announcement aesthetics.
