Dropset Workout Scroll Picker

A vertical scroll picker designed for selecting workout types. As the user scrolls through the list, the active item snaps into the center, scaling up and transitioning from a dimmed gray to a bright white text color. A circular arrow button smoothly fades and slides in next to the active item. Simultaneously, a helper text description at the bottom of the screen dynamically crossfades to match the selected workout type, while a progress indicator at the top tracks the step.
