The house contract for every image call: sizes, edits, text in image.

Write GPT Image 2 prompts for PicX Studio. Use for every generate_image and edit_image call — photoreal scenes, product shots, posters, logos, infographics, UI mockups, text rendered inside an image, retouching and cleanup edits, virtual try-on, style transfer, sketch-to-photo, and character consistency across a series. Covers the five-slot prompt template, the change/preserve pattern for edits, exact-text handling, and the size and credit contract. Use when the user asks for an image, a picture, a photo, a poster, a mockup, a thumbnail, or wants an existing image changed.
The exact brief that produced the image above.
A photographic still life on a warm bone-white sweep, filling the frame. A single matte deep-green ceramic sphere rests on a pale travertine cylinder, lit by one large softbox from the upper left that lays a soft gradient down its curve and throws a long crisp shadow to the right. Beside it, four small flat colour chips lean against the sweep in a neat row. Bright high-key studio light, extremely sharp edges, shallow depth of field, 100mm macro perspective, bone and sage palette, no text, no props.
