"""Integration tests for GET /carveout/{upc}/territory/structured.

This endpoint optionally accepts GRASS auth headers (Grass-Account-Type /
Grass-Account-Id). When neither is present the request proceeds without an
ownership check; when only one is present, or the type is invalid, the
GrassHeaders validator rejects the request with 400. Previously untested.
