Review the linked Figma design for the Account Options screen, then locate the existing screen and its account-related actions in the mobile app. Check how the new action sheet is presented elsewhere before updating this screen. Done means the screen matches the design, uses the new action sheet, and its account actions are connected; acceptance criteria still need to be defined.
