+"""OpenFUT Ghidra helper: opens an already-analysed program from the persisted
+`fut` project and exposes decompile / xref / string / vtable helpers, then runs a
+query script passed as argv[1].
+
+Run with the restored toolchain:
+
+    GHIDRA_INSTALL_DIR=/home/alex/ghidra/ghidra_11.1.2_PUBLIC \
+      /home/alex/re-venv/bin/python tools/re/ghidra_env.py <query.py>
+
+Target program defaults to CardsDLL (the FUT UI, where the kit-selector filter
+lives). Override for powdll (the EASFC/POW layer):
