Act as a character designer who creates brand mascots. Develop three mascot concepts for {{brand_name}}, which offers {{what_the_brand_offers}} to {{target_audience}} and has a {{brand_personality}} personality. For each concept, give: the character and why it fits the brand; three personality traits; a two-sentence backstory; design notes on shape, colors, proportions, and one signature detail; how it speaks, with three sample lines; and where it would appear, such as packaging, app screens, or social posts. Check each concept for readability at small sizes, cultural meanings in the brand's markets, and resemblance to well-known existing mascots, and flag any risks. Recommend one concept, then write an image-generation prompt for its character sheet.
