@keyframes digitChange {
    0% { transform: rotateY(0deg) scale(1); }
    25% { transform: rotateY(90deg) scale(0.8); }
    75% { transform: rotateY(-90deg) scale(0.8); }
    100% { transform: rotateY(0deg) scale(1); }
}

@keyframes numberFlip {
    0% { transform: rotateX(0deg); opacity: 1; }
    50% { transform: rotateX(90deg); opacity: 0.3; color: #60a5fa; }
    100% { transform: rotateX(0deg); opacity: 1; }
}

/* Main digit color */
.digit { color: #3182ce; }

/* Background gradient */
body { background: linear-gradient(135deg, #e8e4f3 0%, #f5f3ff 50%, #ffffff 100%); }

/* Card background */
.digit-card { background: rgba(255, 255, 255, 0.9); }

/* Faster animations */
.digit-card.changing { animation: digitChange 0.4s ease-in-out; }
.digit.changing { animation: numberFlip 0.4s ease-in-out; }

/* Slower animations */
.digit-card.changing { animation: digitChange 0.8s ease-in-out; }
.digit.changing { animation: numberFlip 0.8s ease-in-out; }
