产品视觉 GPT Image 2 提示词：Minimal Abstract Tech Logo Poster

A minimalist abstract graphic poster with a wide 16:9 composition, featuring a soft pastel lavender and pale gray background made of 6 broad horizontal bands with subtle left-to-right gradient shifts. Place a single bold black abstract symbol in the exact center, resembling a stylized curved geometric mark or cropped ribbon-like logo, with a flat top, a sweeping downward curve, and a compact base. Keep the design extremely clean and sparse, with no text, no shadows, no texture, and no extra elements. Use smooth vector-style edges, muted modern branding aesthetics, and a calm contemporary tech visual language.
