Typographic design token generation

Tokens are how a type scale survives contact with a codebase. A scale that isn't enforced is a suggestion.

1. When to invoke

• Turning a type scale into tokens, CSS variables, or theme config.
• Naming typographic tokens.
• Exporting type across platforms (web, iOS, Android).
• A token set has accumulated arbitrary values, or design and code disagree.

Do not invoke to design the scale (hierarchy-and-scale) or choose the face (typeface-selection). Tokenize decisions already made.

2. Required context
