"""Fixtures for the Datadog logging suite.

These tests drive the Datadog batch-send path (#25663) directly against the real
Datadog logs intake with synthetic events - no LLM calls, no proxy, no log
read-back - so they need only the shipping credentials DD_API_KEY + DD_SITE
(DD_SERVICE is an optional tag). No Datadog Application key is required, and they
skip when the shipping credentials are absent from the environment.
