Duolingo 50 Day Streak Animation

This high-energy milestone animation celebrates a 50-day streak. It begins with a stone egg cracking open to reveal a fiery mascot. The mascot bursts upward in a full-screen explosion, transitioning the background to solid orange. A rapid number ticker counts up from 0 to 50 with bouncy physics. Once settled, the weekly calendar slides up from the bottom, and the completed days light up with a staggered checkmark animation. Finally, the primary action buttons slide up into place, completing the rewarding sequence.
