Flexible Design Token Naming

You can now use space and dash characters in token names, so names like my brand colors or my-brand-colors are valid.
However, using spaces in token names is generally not recommended because it can create issues with certain programming languages and make tokens harder to reference in code. To avoid these issues, using camel case or kebab case is better when creating multi-word token names.

Camel case involves capitalizing the first letter of each word after the first, like "fontSizeLarge". Kebab case involves separating words with hyphens, like "font-size-large". So, instead of using a token name with spaces such as "color primary", you could use kebab case and name it "color-primary". This approach makes it easier to reference the tokens in code and eliminates potential issues with spaces in programming languages.
