Duolingo 185 Day Streak Animation

The animation begins with a greyed-out flame icon and the number 184 on a dark background. The flame suddenly ignites, scaling up and bursting with colorful particles. Simultaneously, the number counter rolls up to increment to 185 with a bouncy spring effect. Below, a weekly calendar tracker slides up, and a checkmark pops into place on the completed day. Finally, a prominent 'Continue' button slides up from the bottom to complete the sequence.
