Retro ChatGPT Images 2.5 Announcement Poster

Create a clean retro-modern announcement poster on a horizontal 16:9 canvas with an aged off-white paper background, subtle folds, creases, scuffed edges, and light grain. The composition is split into a large text block on the left and abstract geometric art on the right. Left side: bold black Swiss-style sans-serif headline in three stacked lines reading “Introducing” then “ChatGPT” then “Images 2.5”; use heavy weight, tight leading, left aligned, occupying the upper-left/middle area. Beneath it, add a smaller bold red subtitle reading “A new era of image generation.” Right side: create exactly 3 geometric elements: 1 large red circle near the upper right, 1 deep blue rectangle below it aligned toward the lower right, and 1 thin vertical black line running between the text area and shapes, extending from near the top of the circle down through the blue rectangle. Use minimalist Bauhaus-inspired layout, strong primary colors, crisp edges, slight print texture, and no extra icons, logos, or additional text. Customize the headline as {argument name="headline text" default="Introducing ChatGPT Images 2.5"} and the subtitle as {argument name="subtitle text" default="A new era of image generation"}.
