Implemented in 3a92b14 (plus cef9fa1). I fixed the failing release post by removing the MDX-breaking malformed summary lines, hardened .github/workflows/automated-release-blog-post.yml to sanitize scope-summary input and block incomplete HTML fragments, and updated .github/copilot-instructions.md with an explicit MDX-safety + validation guardrail for automated release posts.
