Summary

Updated prescriptive guidance for sustainability prioritization, including organizational/SCP/OU level prioritization, resource allocation for generative AI, and network access pattern optimization

Security assessment

Changes focus on sustainability optimization (carbon impact reduction, resource efficiency) without any security context. Added guidance covers workload prioritization, serverless preferences, and generative AI efficiency with no mention of vulnerabilities, threats, or security controls.
