update exe GUI build

 ## Notes
 
 - Dashboard: click **启动** to start acquisition; `Q` quit, `R` reset, `S`/`E` record, `Esc` fullscreen.
+
+## Windows standalone folder (CPU-only)
+
+Build a portable folder with bundled Python, packages, `config/`, and `assets/`:
+
+```bat
+conda activate py310
+pip install -e ".[gui]"
+pip install nuitka ordered-set zstandard
+
+build\build_gui_win.bat
+```
+
+Output:
+
+```
+dist/OrisysDashboard/
+  OrisysDashboard.exe
+  config/
+  assets/
+  README.txt
+  (+ bundled DLLs and runtime files)
+```
+
+Run:
+
+```bat
+cd dist\OrisysDashboard
+OrisysDashboard.exe --video path\to\video.mp4
+```
+
+After building, smoke-test bundled files and `--help`:
+
+```bat
+python build\verify.py --gui-dist
+```
+
+Manual QA on a machine without Python:
+
+1. Launch `OrisysDashboard.exe` — dashboard window opens
+2. Play a bundled or local video — 3D mesh and charts update
+3. Confirm default config resolves to `config\dd02-ov.json`
+4. Toggle settings (log, displacement arrows, thresholds)
+
+Notes:
+
+- One-folder layout is recommended (not a single-file exe) for Open3D + PyQt5 reliability
+- CPU-only: CUDA/CuPy are excluded from the build
+- Expect a large folder (Open3D, OpenCV, SciPy, Qt)
+- Frozen path resolution lives in `examples/app_paths.py`
