 Runner: `eulernest` — self-hosted Raspberry Pi, ARM64, Ubuntu 22.04. Docker image: `git.eulernest.eu/conformallab/ci-cpp:latest`. `test-cgal` and `quality-gates` both need `test-fast` to pass first (`needs: test-fast`).
 
 `quality-gates` runs four required structural gates: `license-headers.sh`, `cgal-conventions.py`, `codespell.sh`, `shellcheck.sh --strict`.  Seven more gates (clang-format, cmake-format, cppcheck, sanitizers, clang-tidy, multi-compiler, reproducible-build) are local-only — see `scripts/quality/README.md`.
