The Typography record contains everything about fonts rendering, including character rendering. You probably won't use it as is, but instead using Box.typography which automatically generate an empty Typography record. You can then use modifiers. I.E.

Box.typography
    [ Typography.color Color.white
    , Typography.italic
    ]

Represents the possible decorations of the text. It can be None, Underline or LineThrough. They are created by noDecoration, underline and lineThrough.
