Fuse Intro Value Prop Cycle Animation

The onboarding screen features an automatic vertical ticker that cycles through key value propositions including Spend, Earn, Save, Pay, and Invest. As each item moves to the center active position, it scales up, transitions to a solid dark color, and reveals its corresponding colored icon. The inactive items above and below are styled with reduced opacity, smaller scale, and a soft blur, creating a strong depth-of-field effect. The transition uses a snappy vertical slide with a subtle spring overshoot, while a soft blue gradient background gently shifts behind the content.
