Epische Senna vs. Prost Gladiator poster

An epic cinematic poster in a dark golden bronze palette, styled like a mythic gladiator movie poster merged with vintage Formula 1 iconography. Two legendary rival drivers face away from each other in mirrored side-profile bust portraits at the top half of the image, one on the left inspired by Ayrton Senna and one on the right inspired by Alain Prost, both depicted as heroic Roman gladiators with weathered bronze armor, dramatic shoulder plates, and racing colors draped as cloaks. The left figure wears green, yellow, and blue accents, and the right figure wears blue, white, and red accents. Their faces are mostly in shadow, lit by intense backlight through storm clouds, creating a solemn, monumental mood. Behind each driver hangs 1 vertical banner, for a total of 2 banners: the left banner is dark green with a large gold S, the text "SENNA", "#12", and a cursive signature; the right banner is dark blue with a large gold P, the text "PROST", "#1", and a cursive signature. Centered near the top, in elegant serif French text, place the line "DEUX LÉGENDES. UN SEUL TRÔNE." with a small gold Formula 1 emblem and laurel motif below it. In the central sky, add 2 stacked lines of French text reading "RIVAUX SUR LA PISTE." and "LÉGENDES POUR TOUJOURS." The main title dominates the middle in huge metallic serif lettering: "{argument name="headline text" default="SENNA vs PROST"}", with a sword-like vertical separator for "vs". Beneath it, a subtitle in French reads "LE COMBAT ULTIME DE LA F1". The lower half shows a colossal Roman colosseum packed with spectators, flags, arches, dust, smoke, and dramatic perspective lines converging on the center. At the exact center of the arena stands 1 large victory banner with the words "VICTOIRE GLOIRE HONNEUR" in gold. In the foreground, place 2 front-facing late-1980s Formula 1 cars charging toward the viewer on a dirt-covered arena floor, throwing dust. The left car is associated with Senna and features red-and-white Marlboro-inspired livery, Shell branding, and the number 12 on the nose, with the driver wearing a yellow helmet. The right car is associated with Prost and features matching red-and-white Marlboro-inspired livery, Shell branding, and the number 1 on the nose, with the driver wearing a white helmet. At the very bottom, add the line "1988. 1989. 1990." and below it "L’HISTOIRE S’ÉCRIT À PLUS DE 300 KM/H." Include a small ornamental laurel decoration under the final line. Use hyper-detailed textures, dramatic storm clouds, god rays, flying dust, intense contrast, symmetrical composition, ultra-polished poster design, heroic scale, and a timeless legendary atmosphere.
