产品视觉 GPT Image 2 提示词：Minimal Magnus Effect Infographic

{"type":"educational physics infographic poster","topic":"The Magnus Effect","style":"minimal academic poster, premium textbook-meets-modern design, clean symmetry, balanced spacing, soft neutral cream background, thin teal border, elegant serif typography for headings, minimalist sans-serif for explanatory text, limited palette of teal, muted gold, dark gray, and light beige","layout":{"orientation":"square poster","sections":[{"title":"THE MAGNUS EFFECT","position":"top center","count":1,"labels":["main title"]},{"title":"1. THE PHENOMENON DEFINED","position":"upper section","count":2,"labels":["definition text block","small top-right icon showing a spinning ball with a curved arrow and a gold force label F_M"]},{"title":"2.
