Create an original image of [Subject] with a primary palette of [Palette]. Create a smooth mesh gradient background with light grain in places so it doesn't look too plastic. Put the visual weight in the lower right and keep the upper left evenly lit for a dark title; keep transitions soft, generate no specific objects or symbols, and make sure the colors still feel ordered at thumbnail size. Use a 4:5 vertical format with a clear visual hierarchy, keeping details subordinate to the subject and leaving room for layout later. Do not generate text, logos, signatures, or watermarks; this is a concept example, not a real product photo. If I provide a real product reference, follow its structure and colors; if information is missing, do not invent selling points. After generating, check the edges, object connections, perspective, and lighting; when adjusting, change only one factor at a time.

Check for banding, muddy gray areas, or excessive contrast. Zoom in to inspect the edges, then confirm the aspect ratio and layout space.
