Design a high-fidelity mobile app screen viewed straight on, with no perspective or angled view. Use Belong branding (vibrant pink, orange, purple gradient) on a clean white background with flat, modern UI. The layout should follow a clean, grid-based structure. At the top, include the Belong logo and a circular user profile photo with the name "Stella Anderson" and a label that says "Verified Fan." Below, display a fan points counter and a tier badge labeled "Superfan Level 3." Show a horizontal row of earned badges (e.g., "Challenge Champ", "Top Listener", "Drop Collector") in a flat icon style. Then include a vertical scrollable list of previously claimed rewards, featuring: VIP Ticket, Signed Merch, Meet & Greet Pass each with a visual icon and timestamp. Include a progress bar for "Next Reward Unlock" and a CTA button that says "View Upcoming Rewards." All UI elements must sit flat on the screen, no 3D effects or perspective. Show a minimal, thin, vector-style phone outline around the UI. The visual should be production-grade, clean, and ready for a real app. Use flat vector design with faint gradients and soft shadows only for depth.
