The CGAL test build is too heavy for the eulernest runner — most recent runs OOM during CGAL+Eigen template expansion at -j1/1600 MB rather than exposing real regressions. Gate the job off with `if: false` and a DISABLED-2026-05-26 comment block, matching the pattern already used for doxygen-pages.yml and perf-compile-time.yml. test-fast and quality-gates keep running on every push/PR; workflow_dispatch reruns of test-cgal still work from the Gitea UI.
