 Input and TextArea now use `state` instead of `error`, letter-based sizes, `prefixIcon`/`suffixIcon` instead of `startAdornment`/`endAdornment`, and an optional clear action. Fields now provide associated label and helper text composition, while NumberField adds nullable values and bounded keyboard and stepper controls.
