/**
 * Bursty rate limiter that wraps two underlying limiters. The first is the
 * steady-state limiter; if it rejects, the bursty limiter is consulted
 * to grant short-term burst capacity. Useful for "5 req/sec normally,
 * but allow occasional bursts of up to 15 within 10 sec" patterns.
 *
 * Ported to TypeScript from upstream BurstyRateLimiter. See
 * `THIRDPARTY-LICENSES.md` for attribution.
