Promo Effect v2.0 Prompt for Profile Screenshot Composition

A technical prompt structure for Nano Banana Pro's 'Promo Effect v2.0' feature, designed to composite a character image onto a user's profile screenshot. The prompt enforces specific rules, such as ensuring the 'Follow' button text is present, maintaining background structure, and defining the character's pose (sitting, pointing to the account name and the 'Follow' button). This prompt is highly specialized for UI manipulation and image composition.
