This is a documentation-only Astro Starlight helper, with the main caution that some manual troubleshooting snippets can delete local project artifacts or stop a local process if copied blindly.
Install this if you specifically want help with Astro Starlight documentation sites. For a generic docs-site project, first confirm that Astro/Starlight is the desired stack. Before running cleanup commands, verify you are in the project root and understand that node_modules, package-lock.json, .astro, and dist may be removed and regenerated; inspect any process before killing it. Review optional integrations before adding external analytics, search, auth, or hosting services.
