Exports Style, which is a React component that renders a CSS style string as a <style> element in the <head> of the document optionally specified by props.ownerDocument. Keeps a per-document global registry of styles being rendered so that the same string of CSS will only be rendered as a single <style> element, no matter how many times the <Style> element with that string appears in the React component tree.
Also exports useful CSS string literals, such as SYSTEM_UI_FONT which can be used as font-family: ${SYSTEM_UI_FONT}; to specify the appropriate UI font for the current OS and browser.
