Utilities
Utility classes are classes that do one thing, and one thing well. They are different class utilities, like the one used in layouts layer.
Note: Feo.css offers a very limited set of utility classes. The expectation is that most design tokens will not remain, especially colors. Therefor, only common utility classes unrelated to design tokens are given, and a limited set of utility classes based on the --token-size-{z} and --token-bp-{z} tokens.
