   They're free-threaded wheels, but they still enable GIL when imported. You need to also mark the module as freethreading-compatible.

   $ uv run --with=selectolax -p 3.14t python
   Installed 1 package in 7ms
   Python 3.14.2 free-threading build (main, Dec  9 2025, 19:03:17) [Clang 21.1.4 ] on linux
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import selectolax
   <frozen importlib._bootstrap>:491: RuntimeWarning: The global interpreter lock (GIL) has been enabled to load
   module 'selectolax.lexbor', which has not declared that it can run safely without the GIL. To override this
   behavior and keep the GIL disabled (at your own risk), run with PYTHON_GIL=0 or -Xgil=0.

   I've enabled it for the dev build, but I'm not sure if it will work correctly.
