The fastest route to a real opinion is something you can click. We ship working code in week one, not a slide about what week one might contain.
Anything worth designing twice is worth designing once properly. Tokens, primitives, constraints — the boring layer that makes the rest cheap.
Two or three people who've all touched production. No account layer, no relay of intent through a project manager.
We hand over documentation your team actually reads and a codebase they can extend without calling us. That's the point.
