DangerJS is triggered with each push event to a Pull Request and modify the contents of this comment.

Please consider the following:
- Danger mainly focuses on the PR structure and formatting and can't understand the meaning behind your code or changes.
- Danger is not a substitute for human code reviews; it's still important to request a code review from your colleagues.
- Resolve all warnings (⚠️ ) before requesting a review from human reviewers - they will appreciate it.
- Addressing info messages (📖) is strongly recommended; they're less critical but valuable.
- To manually retry these Danger checks, please navigate to the Actions tab and re-run last Danger workflow.
