+Component prop types are now exported: `AvatarProps`, `CheckboxProps`, `RadioProps`, `StatusProps`, `TooltipProps`, `MenuProps`, `ModalProps`, `EdgeLabelProps`, `NodeIconProps`, `NodeDescriptionProps`, `NodeAsPortWrapperProps`, `SegmentPickerProps` (with its controlled/uncontrolled variants), the NavButton variant prop types, and `DatePickerProps` now covers the component's full runtime surface (`value`, `defaultValue`, `placeholder`, `valueFormat`, `type`, `error`). Supporting types used in those signatures (`Shape`, `IconNode`) are exported as well.
