Staging check override

Use this when staging is confirmed down and .github/workflows/docs-staging-check.yml would fail every merge.

The why is in staging-check-override.

How to skip

1. Confirm staging is actually down (GET /health or a known buyer call).
2. Run docs-staging-check via workflow_dispatch.
3. Set skip_reason to a one-line cause. That becomes SPOT_STAGING_SKIP_REASON.
4. The job prints STAGING_CHECK_SKIPPED reason=... and a ::warning:: annotation.

How to re-enable

Dispatch the same workflow with an empty skip_reason. The runner executes sdks/consistency/fixtures/calls.json against SPOT_STAGING_BASE_URL.

Ownership: docs/API owners (DOCS_API_OWNERS). Re-run within one business day of staging recovery.
