无法下载Tectonic Sandbox：请求提供有效下载地址

Hey there, sorry to hear you hit a snag with the broken Tectonic Sandbox download link! Let me share some reliable alternatives to get your hands on the sandbox since the official coreos.com links are no longer active:

• Check GitHub's CoreOS Archive Repos
  Tectonic was a CoreOS project, and most of its historical assets are archived on GitHub. Head over to the CoreOS organization's archived repos and look for the tectonic-sandbox repository. Navigate to the Releases section—you’ll find the old sandbox packages available for download there. Keep in mind that since CoreOS is now part of Red Hat, some repos might be marked as archived, but the release assets should still be accessible.

• Leverage the Internet Archive (Wayback Machine)
  The Wayback Machine has snapshots of the original coreos.com/tectonic/sandbox page from when it was active. Search for that URL in the Wayback Machine, pick a snapshot date that falls before the link was taken down, and you’ll be able to access the original download links from the archived page. This is a great way to grab the exact version referenced in your tutorial.

• Consider Modern Alternatives (If Flexibility Is Allowed)
  If you don’t strictly need the legacy Tectonic Sandbox, Red Hat’s OpenShift Local (formerly CodeReady Containers) is the modern replacement for local Kubernetes/OpenShift testing. It offers similar functionality to Tectonic Sandbox but with active support and regular updates.
