  Style and hygiene checks: prettier (via the repo's format:check script),
  eslint (via the repo's lint script), and conventional-commit linting when
  a commitlint config exists. Each check is --if-present/config-gated, so
  repos opt in by defining the script or config. Run after node-checks in
  the same job (needs node_modules from npm ci).
