✋ Uh oh! Detected changes to the files in the \`/translations\` directory.'
The content in this directory is managed by our translation pipeline and should not be edited directly in the repo.
For more information on how the localization process works, see \`translations/README.md\`.
If you have accidentally edited these files, you can unstage these changes on the command line using \`git restore --staged translations\`.
If you are performing a merge from \`main\`, you should bypass this hook by using \`git commit --no-verify\`.
If you need to edit translated files often, you can set \`ALLOW_TRANSLATION_COMMITS=true\` in your .env file.
