Nano Banana Pro E-commerce Promo Banners: Pin Every Text Element in Place

Banners differ from posters mainly in having more text elements (headline copy + discount + CTA), so the position and size hierarchy of every element must be pinned down explicitly, or the model will arrange them however it likes. The discount number is the banner's lifeline, so locking it in quotes plus a 'not a single character may be wrong' declaration is essential. Generate the 16:9 version first, then ask in the same conversation to 'apply the same design to a 1:1 version' — this tends to be more stable than requesting two sizes from the start. Social media marketers running seasonal campaigns can save this as a template and just swap three variables each time to produce new banners.
