 """Acceptance test: VPC v1 marker-based pagination over the real API.
 
-Creates several VPCs and verifies that ``list_vpcs(limit=2)`` walks
-through every page and returns all of them. Robust against other VPCs
-that may already exist in the tenant: the test only checks that its
-own resources are present in the result, not the total count.

+The test skips itself if the tenant's free VPC budget is insufficient,
+rather than failing on a 409 from OTC's quota.
