# ubuntu-24.04 runners restrict unprivileged user namespaces via AppArmor,
# which Chromium's sandbox needs to launch. action-linkspector (used in the
# pr job above) works around this itself; a bare `npx linkspector` here
# does not, so it crashes with "No usable sandbox!" on every scheduled run.
# See https://chromium.googlesource.com/chromium/src/+/main/docs/security/apparmor-userns-restrictions.md
