- ARM runs on GitHub's ubuntu-24.04-arm runner (free for public repos), set
up by arm-runner-setup.sh: Incus 6.0 LTS from Zabbly (key pinned, APT
pin), screenshots through Playwright. ARM rows are shown but never count:
not in the headline, the check, the review or the approval, and the job
runs with continue-on-error.
- var_arm64=no is not built on ARM; unset is built with var_arm64=yes.
- arm-script-test.yml builds one script on ARM by hand, posting nothing.
- Update test: only the versions update_script checks are set back.
- The screenshot browser gets a writable HOME.
