• Before: scripts/affected-tests main failed on npm test --prefix site with ERR_MODULE_NOT_FOUND (marked) before installing site dependencies.
  After: after npm ci --prefix site, npm test --prefix site passed (46.61s; docs:check, glossary/manual checks and Playwright suite).
• The Linux-only Rust targets run in GitHub Actions CI (thirdshift targets Linux only on macOS).
• git diff origin/main --check is clean.
