Scene: A clean, minimal 2D motion graphics animation in a medical green (#00AF06) and white color palette. No human characters, no phone UI, no realistic elements. Animation Sequence (4–5 seconds): White background with soft green circular accents. A large green circular outline smoothly scales up from the center. Small healthcare-themed flat icons (medicine strip, pill, prescription paper, rupee symbol ₹, plus icon) slide in from different directions and orbit around the circle. Thin green lines connect the icons, forming a clean circular composition. The icons gently bounce into place with subtle easing. A bold green challenge badge pops into the center with a smooth scale animation. The text "Let's Do A Challenge!" appears using a type-on animation with a slight upward fade. A thin green underline draws itself beneath the text. Background elements continue with a very subtle floating motion to keep the frame alive.
