Provide intuitive cart quantity controls

To minimize friction during the shopping experience, it’s crucial to let users easily edit the number of items in their cart.^[1] If they make a mistake, they shouldn't have to restart the entire process, as being forced to do so can significantly diminish the likelihood of completing the purchase.

Particularly for mobile users, adjusting item quantities needs to be user-friendly. Dropdown controls can be cumbersome on smaller screens, leading to longer interaction times. A more efficient solution is to implement an input stepper control. This simple toggle allows users to increase or decrease quantities with just a tap, offering a more intuitive and hassle-free shopping experience.
