 * NG size tokens. They live in the MUI theme, so they only reach the DOM when
 * the theme is built with `muiThemeOptions` — either through
 * `<ThemeProviderFlipper options={muiThemeOptions}>` or by merging the options
 * into the consumer own `ThemeProvider`. The `Typography` component falls back
 * to these values when the theme does not carry them, so the size is never
 * lost — but a consumer theme can only override a token that it declares.
