## Summary
The Crowdin GitHub Action was failing at ~54% progress with the error:
> Failed to build translation. Please contact our support team for help
## Root Cause
The build was attempting to process all target languages configured in
Crowdin, including languages not supported by Mintlify (as defined in
`supported-languages.ts`). Some of these unsupported languages had
translation issues causing the build to fail.
## Fix
Added the `download_language` parameter to the Crowdin GitHub Action to
restrict downloads to only the languages supported by Mintlify:
- fr, ar, cs, de, es, it, ja, ko, pt, ro, ru, tr, zh-CN
## Testing
Verified via Crowdin API that builds succeed when specifying only these
supported languages, while the full build fails.
