5/// A standard HTTP response classifier.
6///
7/// Generally treats all client (4xx) and server (5xx) errors as retryable, with the exception of a few specific client
8/// errors that should not be retried:
9///
10/// - 400 Bad Request (likely a client-side bug)
11/// - 401 Unauthorized (likely a client-side misconfiguration)
12/// - 403 Forbidden (likely a client-side misconfiguration)
13/// - 413 Payload Too Large (likely a client-side bug)
