Start where you are
Four paths in. Pick the one that matches your question.
“I'm starting from zero”
Build a design system, day 1 to day 90.
Eight chapters mapped to a 90-day path. Foundations first, tokens before themes, governance before headcount. Practitioner voice, no theory.
“I need to pick what to build on”
Which design system to choose in 2026.
Five team shapes, five concrete recommendations, the anti-patterns to avoid, and the shifts since 2023 that changed the answer.
“I'm trying to drive adoption”
Why your design system isn't being used.
The hard part isn't building it — it's getting other teams to ship on it. The distribution mechanics, the funnel from discovery to maintenance.
“I'm making ours AI-ready”
Tokens, MCP servers, and agents that ship code.
The 2026 wedge: how to expose your tokens, components, and patterns to Cursor, Claude Code, and v0 without drift. Three pillars, a readiness checklist, and a 1-week migration plan.
