晨跑益处信息图 — 视觉化健身海报提示

生成一份关于晨跑健康益处的精美中文信息图海报，适合社交媒体分享或健康教育展示。 Use it as a Art Conceptuel 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, language, style, canvas, main visual, and layout. 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.
