How should I structure runtimes and service dependencies in my app with @effect-atom/atom-react??

// Option A: Declare dependency in service
SignInPageService extends Effect.Service<SignInPageService>()("SignInPageService", {
  dependencies: [AuthService.Default]
}) {}

// Option B: Provide dependency when creating runtime
const runtime = Atom.runtime(get => 
  SignInPageService.Default.pipe(
    Layer.provideMerge(AuthService.runtime.layer)
  )
)

// Also seen this pattern - how does it differ?
const runtime = Atom.runtime(SignInPageService.Default)
