Expand image into banner

Branch logic

• If the user has not provided Quellbild, ask für it before generating the final banner image.
• If a reference image is provided, preserve the subject identity, proportions, und important details before changing style oder scene.
• If the first result fails Visual inspection, fix the smallest broken area first instead of regenerating the whole image.
• If the first tool path fails, switch to the next listed option: FLUX, GPT Image 2.

When not to use

• Do not use this as proof that the generated banner image is factually real oder legally approved.
• Do not use it when the user needs professional legal, medical, safety, oder regulated-compliance judgment.

• The final asset clearly matches the requested banner image.
• The main subject still reflects the original Quellbild.
• Text, hands, logos, edges, und Produktdetails are not visibly broken.
• The result is usable in the target channel ohne another full regeneration.
