 **Then verify (either path):**
 
 Run `python --version` and `cmake --version`. Fix automatically:
-- **Python not 3.10–3.14**: recreate the env with a correct Python version.
+- **Python not 3.10–3.13**: recreate the env with a correct Python version.
 - **cmake missing or < 3.24**: run `pip install 'cmake>=3.24'` inside the env.
 - **cmake >= 4.0**: works in practice, no action needed.
