I acknowledge that:

I have reviewed the FAQ and confirm that my issue is NOT among them.
I have searched the Ghostty documentation and confirm there doesn't exist a configuration option that solves my issue.
I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.
