Fix Syntax Error in TBG_Refiner.py

[deadpipe]

Thanks for sharing this custom node.

I just installed it and noticed a syntax error during startup.

Fixed it by replacing the inner double quotes ( " " ) with single quotes ( ' ' ) inside the f-strings

Error:

What system are you using? I’m not seeing any issues on Windows ComfyUI 0.21 portable—could this be a Linux-only bug or it's a Python version compatibility issue that affects both platforms, but you might be running different Python versions. 3.12+ has no problem. Python Version Behavior
Python 3.11 and earlier:

F-strings cannot contain the same type of quote used to delimit the f-string itself

f"...{obj.get("prompts")}..." fails because the inner " closes the outer f-string prematurely

Python 3.12+:

F-strings were enhanced to allow quote reuse and more complex expressions

The same syntax would work fine
