/tokens — Design Token System

Audits every hardcoded design value in the codebase, builds or enforces a three-layer token system (primitives → semantic → component), and replaces hardcoded values with tokens throughout.

Token architecture and naming conventions: SYSTEMS.md

If a DESIGN-BRIEF.md exists in the project root: read it before starting. The brief's Color System and Typography fields give you the exact starting point for primitive tokens — use those hex values and font names directly rather than deriving them from scratch.
