Where can I find ms-font-su for Text component

[ademkikaj]

I am trying to reach something like this in React environment:

<span class="ms-font-su ms-fontColor-themePrimary">Big blue text</span>

Is it a good practice to mix Fabric Core with FluentUI? In the FluentUI is noted that:

If you're using Fluent UI React, you may not need Fabric Core. Most of the styles from Fabric Core are also available via CSS-in-JS styling, which is the recommended styling approach with Fluent UI React.

Currently, I am using: <Text variant={"large"} style={{ color:SharedColor.cyanBlue10}}>Big Blue Text</Text> but I am not getting the same results as the above example that uses FabricCore.
