Greetings, I had actually worked on this issue, two months ago, and just realized that I hadn't ever moved the code up. I guess comping back to something later, caused some issues. Which I'm not experiencing on my local copy.

Thanks for sharing your changes here!

I see that the tests are complaining:

______________ ERROR collecting tests/test_content_formatting.py _______________
ImportError while importing test module '/root/project/tests/test_content_formatting.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/local/lib/python3.13/importlib/__init__.py:88: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
tests/test_content_formatting.py:10: in <module>
    from src.content_converter import ContentConverter
E   ModuleNotFoundError: No module named 'src'

We need to teach pytest to find the source files. Probably by adding src/ to the PYTHONPATH?

I don't have a lot of time to work on this right now, but will come back to it.
