Diptych poster of Zoro and Sanji as mate & rival AI Image Prompt

A high-end, diptych-style promotional poster in a realistic, detailed anime style. The left panel, inspired by image_1.png, features {argument name="character 1" default="Roronoa Zoro"} in a three-quarter pose, looking direct. He wears a meticulously detailed {argument name="outfit" default="deep green three-piece suit with intricate gold embroidery"}. He holds a small cup and his three Katanas are in a traditional koshi-ate rig behind him. The left side has a cross-swords logo, text like 'THE PROMISE -OF THE GREEN DEMON-', his name in large font, and his full quote. The right panel, inspired by image_2.png, is a close-up profile of {argument name="character 2" default="Vinsmoke Sanji"}, with the same light, and his signature eyebrow swirl. He wears a black suit with similar gold embroidery and a '66' emblem tie tack. The right side has a fork-and-knife logo, text like 'THE VIGIL -OF THE IRON SOUL-', his name in large font, and his full quote. The panels have a clean, shared off-white background with a subtle marble texture and consistent footer text for 'Eiichiro Oda' and 'ONE PIECE EST. 1997'. The two panels are unified by a central, shared header over the two names: 'MATE & rival', rendered in a gold, calligraphy-style script.
