* requested permits, by an invocation acquire(permits), are served from:

   * - stored permits (if available)

   * How this works is best explained with an example:
   *
   * For a RateLimiter that produces 1 token per second, every second that goes by with the
   * RateLimiter being unused, we increase storedPermits by 1. Say we leave the RateLimiter unused

But if we access the docs UI at the "official" URL using the proxy with port `9999`, at `/api/v1/docs`, it works correctly! 🎉

 * {@link #writeTo} and {@link #readFrom} methods. Both serialized forms will continue to be
