This animation showcases a user ascending the Duolingo leaderboard into the promotion zone. The sequence begins with the list scrolling to position the user. The user's row then smoothly slides upward, overtaking the rank above it. Upon crossing the 'Promotion Zone' threshold, the row's background flashes a vibrant green, green confetti bursts from the sides of the row, and the rank number updates to a green active state, accompanied by a celebratory sound effect.
