Nano Banana App Store Campaign

Build App Store screenshots as ads, not tutorials.

Copy comes before layout. Narrative comes before decoration. The slide should explain itself visually first. The text should sharpen the message, not do all the work.

Use this skill when the user wants a screenshot campaign that:

• starts from the actual app codebase and real screenshots
• needs a consistent visual system across all slides
• uses Nano Banana for the ad treatment
• needs deterministic resizing and contact-sheet packaging

Use Nano Banana only in this skill. Do not switch to other image models. Do not silently fall back to Flash or any lower-quality image path.
