Japanese Anime AI Launch Poster

Create a vibrant Japanese promotional poster for {argument name="brand name" default="Sousaku.ai"} announcing {argument name="product name" default="GPT Image 2.0"}. Use a vertical 3:4 layout with a flashy anime-tech advertising style, bright cyan, blue, purple, pink, and white gradients, glowing sparkles, lens flares, halftone dots, and dynamic diagonal light streaks. On the right side, feature a large half-body anime girl mascot in a futuristic streetwear outfit, silver-white long wavy hair with cool blue highlights, pale skin, blue eyes, a confident smile, and one hand thrust toward the viewer with an extended pointing finger in strong foreshortened perspective. She wears a glossy white and blue jacket over a dark inner outfit, a black choker, layered accessories, and a visible badge or tag with an S logo and the text Sousaku.ai. Her face area is covered by a plain square censor block. On the left, place a large stacked headline in bold Japanese display typography with thick outlines and drop shadows reading exactly: "Sousaku.aiに", "GPT Image 2.0", "が来た！". Below it, add a blue ribbon banner with white text reading "話題の現最強モデル". Under that, add a rounded blue header box with white text reading "GPT Image 2.0のここがすごい！". Beneath the header, create 4 rounded rectangular feature panels stacked vertically, each with a pastel icon circle on the left, Japanese text in the center, and a sample image thumbnail on the right. Panel 1: icon is a speech bubble with a Japanese flag, headline text in pink-red "日本語プロンプトOK", smaller black explanatory text in 3 lines, and a thumbnail of a traditional Japanese street with a pagoda and cherry blossoms. Panel 2: icon is a yellow lightning bolt, headline text in orange "即座に高品質生成", smaller black explanatory text in 3 lines, and a thumbnail of a futuristic neon city at night. Panel 3: icon is an artist palette and brush, headline text in green "多彩な表現力", smaller black explanatory text in 3 lines, and a thumbnail of an anime fantasy girl in a snowy or bright scenic setting, with the face lightly obscured. Panel 4: icon is a magic wand with sparkles, headline text in purple "高い一貫性と精度", smaller black explanatory text in 2 lines, and a thumbnail row containing exactly 3 close-up anime character portrait variants side by side, each face obscured. At the very bottom, add a bold call-to-action on a dark blue strip reading exactly "→ {argument name="call to action" default="Sousaku.ai で試してみよう"}" with the brand name in large yellow letters and the remaining text in white. Make the overall composition dense, polished, glossy, and eye-catching like a social media announcement poster for a new AI image model.
