Found broken `/space` link. Please fix!

there's an issue, i guess.

The issue mentions a broken '/space' link but does not specify where this link is located. Look for references to '/space' in the repository's documentation files, likely in MDX files. Check for any navigation or markdown files that might contain this link. Once found, verify the correct URL and update it.
