- ISO 27001 compliance link: https://learn.microsoft.com/azure/compliance/... → ../../../azure-docs-pr/articles/compliance/...
- ARM templates link: https://learn.microsoft.com/azure/azure-resource-manager/templates/ → ../../../azure-docs-pr/articles/azure-resource-manager/templates/

Using cross-repo relative links for better maintainability and consistent linking strategy.
