+"""Tests the first-run setup decision logic in src/main.py.
+
+The rule that matters: a player is "configured" only when it has REAL server
+settings. A missing file, an empty file, unparseable JSON, missing keys, and
+leftover placeholder values must ALL count as unconfigured, so the app shows
+the setup notice instead of silently trying to reach "localhost".

+Run:  windows\\venv\\Scripts\\python.exe windows\\test_first_run_setup.py
