Modifications by the segspec authors (2026) for use as a demo fixture:
- Reduced from 11 services to 6.
- Removed loadgenerator, adservice, currencyservice, paymentservice,
  emailservice, shippingservice deployments. Their addresses remain
  referenced as env vars on the surviving services so the dependency
  graph segspec extracts is still complete.
- Removed resource limits, probes, ServiceAccount fields, and similar
  metadata not relevant to dependency extraction.
