THIOS: ONE SOURCE OF TRUTH, FIVE SURFACES
Challenge: 6 sub-brands across 4 production sites plus an OnShape CAD source. Drift is the default, not a possibility.
Approach: Five canonical surfaces (DESIGN.md ↔ tokens.json ↔ main.css ↔ design-system.html ↔ OnShape) kept aligned by agent-driven audits.
Result: 5 surfaces in sync · 212 design tokens · 7 drift findings caught in May audit · 1 designer
