• Support multiple brands in applying the system through tokens, theming, and component variants 
• Support multiple brands in onboarding and setup of the ‘brand expression layer’ 
• Balance consistency with brand expression within defined system frameworks 
• Partner with teams to ensure alignment with Helium DS

AI-Enabled Design Acceleration
