Duolingo 127 Day Streak Animation

The animation begins with an inactive grey flame and '126' streak count. A sudden burst of liquid pink and orange shapes morphs the flame into a vibrant, glowing state while the numbers roll up to '127' using a vertical ticker transition. Following this, the 'day streak' text, a weekly progress calendar, a motivational subtitle, and a primary 'Continue' button slide up in a staggered sequence. The calendar days are marked with animated red checkmarks. Tapping the primary button compresses the flame back into a compact icon before transitioning out.
