TypeScript at the boundaries of your app
Where strict types pay off first: API clients, config, and shared DTOs.
You do not need every file fully typed on day one. Focus on the seams: anything that crosses network or process boundaries should be validated and typed.
Zod or similar at the edge plus TypeScript internally catches an entire class of integration bugs before they reach users.
