Create or update a project-level BRANDING.md for apps and digital products, focusing on emotional identity, visual identity, color direction, shape language, typography, UI tone, iconography, illustration style, brand metaphors, product copy, and design do/don't rules. Use when users ask to create a brand guide, define app branding, document product identity, generate BRANDING.md, convert product context into brand direction, or align designers, developers, copywriters, and AI coding agents around a practical visual and emotional brand system.
