DisplayText is used to display text in special scenarios - example usages of DisplayText include empty states, promotional/featured items, etc.
DisplayText should not be used as a replacement for headings/page titles (use the Heading component instead).
The <Typography> component should be used to wrap a group of typography components (<Heading>, <Paragraph>, etc) for cases where you wish to display these components with default margins.
We follow the principle that a component should only be responsible for its own internal spacing - never its external spacing. This means that we're flexible in where our components can be used without having to override margins.
