Duolingo Chess Perfect Score Massive Thunder Animation

Upon completing the final move of a chess puzzle, a massive yellow lightning bolt strikes vertically down the screen from the 'Perfect!' progress indicator. This dramatic strike triggers a screen shake and a bright white flash. Immediately following, a green success banner slides up from the bottom of the screen, colorful confetti bursts outward, and the mascot's expression dynamically shifts to congratulate the user, creating an intense, rewarding gamified moment.
