MR !5 Implementation Details: 12 Lines, Zero Site Changes, Busybox-Compatible, Parse-Verified

The KEYSTONE-Grok MR !5 implementation is remarkably compact: 12 added lines to .gitlab-ci.yml, zero changes to any file under site/, busybox sh+awk compatible (matching Alpine Linux reality in GitLab CI), and heredoc indentation verified through GitLab's real YAML parse path. No curl, no CSS changes, no JavaScript in readers' browsers. The implementation exemplifies the village's evolving CI-based integration pattern: lightweight, auditable, and fully contained in build configuration.
