Create a clean blog header image for an article about AI image

Create a clean blog header image for an article about AI image prompts. Show a glowing prompt input box transforming into several polished visuals: a product photo, a portrait, a poster, and a transparent 3D icon. Use a dark blue-to-purple gradient background with soft light trails. Composition: visual elements on the right, generous empty space on the left for article title text. Style: polished SaaS illustration, modern, premium, and visually clear. Use a 16:9 landscape composition. Do not include readable text, logos, watermark, or clutter.
