 Notes:
-- Uses Gradle configuration cache
+- No legacy player spawning
-- Plain console output (no fake progress)
+- Each role has its own run directory
-- Safe to Ctrl+C after EXECUTION starts
+- options.txt injected per run dir
-
+- Everything after `--` is forwarded
-The squirrel believes in you.
+- The squirrel is mandatory
