• AI-ready specification
• Define components and patterns in a structured, explicit and unambiguous way

• Adviser workflows (fact find → recommendation → submission → review)
• Consumer journeys (discovery → understanding → action
• Design principles (these should guide your work)
• One consistent experience across marketing and product
• Data-first interfaces with a single source of truth
• Clarity and usability over visual decoration
