      The Zuul Filters API provides the core extension point for building
      custom logic into the Zuul gateway pipeline. Developers implement
      inbound, endpoint, and outbound filters using synchronous or asynchronous
      base classes to handle authentication, routing, rate limiting, metrics,
      and response decoration.
