This interaction showcases Wise's highly responsive currency calculator. As the user types, the input text dynamically scales down to fit the screen width, maintaining readability without wrapping. When an input limit is exceeded, the text wiggles horizontally and turns red, accompanied by an error banner sliding down. Deleting characters scales the text back up smoothly. Switching focus between the 'You send' and 'Recipient gets' fields triggers a seamless size swap, where the active field scales up to become the primary focus while the other shrinks, all accompanied by staggered fade-ins of transaction details.
