Three live FX rails · cheapest in roughly two seconds.
Every refetch hits GET /api/quote on the live API, generates fresh sandbox call_id tokens for all three rails, picks the cheapest, and re-renders the animation with the new numbers. The trace-id round-trips so a correlated request log line exists for every render.
