type Unit = Text

tokenize :: Text -> [Token]

Parse a Text into a list of Tokens.

https://drafts.csswg.org/css-syntax/#tokenization

serialize :: [Token] -> Text

Serialize a list of Tokens back into Text.

Serialization "round-trips" with parsing:

tokenize (serialize (tokenize s)) == tokenize s
