assert httpx.Client default timeout is 5.0 seconds across all 4 phases (connect, read, write, pool), unlike requests which defaults to None
assert httpx.Timeout() with no arguments raises ValueError rather than returning the 5.0 default configuration
assert httpx.Timeout(read=10.0) raises ValueError without a positional default argument or all four explicit kwargs
assert httpx.Timeout(5.0, read=10.0) sets read to 10.0 and keeps connect, write, and pool at 5.0
assert passing a 2-tuple (connect, read) sets write and pool to None (unlimited), not 5.0
assert passing a 4-tuple sets connect, read, write, and pool in explicit positional order
assert timeout=None at the request level explicitly disables all timeouts even when the client has a positive timeout configured
assert request.extensions['timeout'] carries the resolved 4-phase dictionary into the transport layer
assert ConnectTimeout, ReadTimeout, WriteTimeout, and PoolTimeout all subclass TimeoutException and RequestError, but not HTTPStatusError
