Awaited<T> and unwrapping nested promise types

type Nested = Promise<Promise<Promise<string>>>;
type Flat = Awaited<Nested>;

export async function loadUser(): Promise<{ id: string; name: string }> {
  return { id: "1", name: "Ada" };

Unwrap Promise<Promise<Promise<T>>> down to T in one step, the way await does at runtime, using TypeScript's built-in recursive helper.
