design tokens⁽³⁾

Tokens evolve from static values (colors, spacing) to behavioral ones: motion curves, layout logic, and adaptive personalization rules. Enables AI agents to generate UI within system constraints — the infrastructure layer that keeps generative design on-brand.

Semantic design variables replacing hardcoded values across design systems. Enables multi-brand scalability and bridges the gap between design intent and implementation.
