Google Fonts 日语信息图海报 — 现代扁平设计提示

此提示生成一份简洁、扁平风格的日语信息图海报，用于介绍 Google Fonts，适用于社交媒体、幻灯片或教育设计项目。 Use it as a コンセプトアート starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, topic, style, text, layout, cards, and lower band. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
