typescale

This is a standalone composable skill. It works two ways:

1. Standalone — user runs /gsp:typescale "Inter" --ratio 1.25 directly, gets a production-ready type system
2. As a building block — identity phase detects existing typography files and reuses them

Visual companion: https://typescale.com/ — users can preview ratios interactively there, then feed the values here.

Input: Font family, ratio, and options (args or interactive) Output: typography.md foundation chunk + tailwind.typography.css (Tailwind/shadcn) or typescale.css (vanilla) in the target directory Agent: None — mathematical scale generation, handled inline
