Miles Numbers Countdown Flip Animation

The interaction begins with a fullscreen countdown timer. Large, minimalist numbers slide vertically upwards to transition from 3 to 2 to 1. The upcoming number rests below the active number, heavily blurred to create depth. As the countdown progresses, the blurred number slides up into the center focal point, sharpening instantly, while the previous number slides up and fades out. Once the countdown reaches zero, the final number slides out of frame, and the workout dashboard elements (distance, time, pace, and a stop button) smoothly fade and slide into place.
