A realistic dark-mode smartphone chat interface screenshot displaying two Japanese prompt-and-response exchanges about generative ad design against a nearly black background. At the top right, a rounded light-gray user bubble contains the exact Japanese text: 「日本語の幼稚園の広告画像を、トンマナ違いで4種類並べて画像生成して。プロデザイナーが作ったトレンドのデザインで。アスペクト比は16:9」. Directly beneath it is a rounded rectangular image preview showing a 2x2 grid of kindergarten advertisement layouts in soft pastel tones: top-left features a soft, airy layout with a close-up profile of a young child in morning sunlight and handwritten Japanese copy; top-right features an energetic outdoor ad with four children running under a blue sky with bold typography; bottom-left shows a modern kindergarten campus building with children on a grass lawn and a speech-bubble text box; bottom-right shows an illustrated large green tree with children and parents under a sky-blue background. Overlaid on this preview are a small gray circular button labeled 「編集」 at the bottom-left and an upload/share icon at the bottom-right, followed by a row of four action icons below: copy, thumbs up, thumbs down, and more options. Further down, a second right-aligned bubble displays: 「日本語の健康食品の広告画像を、トンマナ違いで4種類並べて画像生成して。プロデザイナーが作ったトレンドのデザインで。アスペクト比は16:9」. Beneath it is a second 2x2 grid preview of health food ads: top-left shows an airy minimalist wellness ad with a woman and pale green accents; top-right shows a luxurious black-and-gold supplement ad with gold particles, serif typography, and a price badge showing [980円]; bottom-left shows a soft pink beauty supplement with translucent floral textures; bottom-right shows a green juice smoothie with fresh vegetables and product packaging. High-resolution mobile UI layout with crisp Japanese typography and generous vertical spacing.
