Create an original, production-quality image-generation prompt for this brief: create a scroll-stopping carousel cover that communicates one idea instantly on mobile. Inputs: {{topic}}, {{audience}}, {{headline}}, {{brand_style}}, {{platform}}. Define the focal subject, environment, composition, camera or illustration perspective, lighting, material behavior, depth, color mood, and negative space. Preserve exact product, architecture, logo, packaging, UI, or person-reference details when supplied; do not redesign them unless asked. Produce a clean editorial layout with one hero visual, large readable headline, subtle brand cue, high contrast, and safe margins for mobile cropping. The final visual should look intentional at advertising or editorial quality, not like generic AI art. Avoid distorted anatomy, duplicate objects, fake text, clutter, plastic skin, inconsistent reflections, impossible structure, and excessive effects. If copy will be added later, keep a clean text-safe zone and do not render small body copy into the image.
