Ketchup Wheel Picker

This interaction features a vertical wheel picker designed for selecting Pokémon types. As the user drags vertically, the list of type icons rotates along a subtle circular arc. Icons dynamically scale up and gain full opacity as they enter the center active zone, while inactive icons shrink and fade into the background. Upon release, the wheel snaps smoothly to the closest item with a subtle spring settle, updating the central relationship formula and effectiveness text.
