 ### Infield button and stepper fast follows
 
 - Updated infield button disabled border color to use `--spectrum-gray-300` for spectrum-two theme and `--spectrum-gray-200` for other themes.

The changes include correcting the background colors for the stepper infield buttons in the hover and keyboard focus states (updating them to `gray-200`), as well as correcting the chevron icon color within the keyboard focus state (updating to `gray-900`).
