I need a complete Figma file that maps out every key flow for a mobile-first marketplace. The core screens and components I expect you to cover are: • Onboarding and authentication • User profiles featuring a profile picture, public reviews, and a wish-list section • Product Listing Page (PLP) and Product Detail Page (PDP) with clear CTA hierarchy • Seller “boosting” options to highlight products • Secure payment integration flow, including checkout and order summary • Delivery-partner hand-off and real-time tracking screens • Light / dark mode variants and a reusable component library Please keep the style modern, clean, and consistent with current iOS and Android guidelines. A structured layer naming convention and auto-layout usage are essential so future handoff to developers is painless. Deliver the editable Figma file plus a brief walkthrough explaining the design system and how each flow connects.
