   Use the Python script at `assets/post_linear_comment.py` to handle the entire Linear API interaction. This avoids all shell escaping issues with GraphQL (`$input`, `CommentCreateInput!`) and markdown content (backticks, `$`, quotes).
 
   The script reads `LINEAR_CLIENT_ID` and `LINEAR_CLIENT_SECRET` from environment variables (set from GitHub Actions secrets), obtains an OAuth token, checks for duplicate triage comments, and posts the comment.
