"""PyInstaller 打包配置：SVFS Client（PySide6 + QtWebEngine 插件客户端）。

用法（或直接用 packaging/build.py 编排）::

    uv sync --extra gui
    uv pip install pyinstaller
    uv run pyinstaller --noconfirm packaging/svfs_client.spec
    # 目录版产物: dist/SVFS-Client/SVFS-Client.exe

单文件版（QtWebEngine 启动前要先解包到临时目录，明显更慢）::

    SVFS_ONEFILE=1 uv run pyinstaller --noconfirm packaging/svfs_client.spec

QtWebEngine 的资源（icudtl.dat、qtwebengine_resources.pak、locale、
QtWebEngineProcess.exe）由 pyinstaller-hooks-contrib 的 PySide6 钩子自动收集，
本 spec 不需要手工列——但要保证 PyInstaller >= 6。

# 体积裁剪（白名单制）：PySide6 的钩子会把 wheel 里**所有** Qt 模块的
# DLL/pyd 整包搬进来（Quick3D 全家、QuickControls2、Pdf、OpenGL、Svg……
# 约 70M 的没人用的东西），黑名单删不干净，这里只留依赖链上的：
#
# * Qt6WebEngineCore 实测导入（objdump）：Core/Gui/Network/Positioning/Qml/Quick/
#   WebChannel；WebEngineWidgets 另需 PrintSupport/QuickWidgets/Widgets；
#   Qt6Quick 另需 Qt6OpenGL 与 QmlMeta/QmlModels —— 这些必须留。
# * pyd 只留 Python 层真实用到的（实测 import 链）：QtCore/QtGui/QtWidgets/
#   QtNetwork/QtPrintSupport/QtWebChannel/QtWebEngineCore/QtWebEngineWidgets；
#   其余绑定（Qml/Quick/QuickWidgets/Positioning/OpenGL）没有 Python 调用者，
#   它们的 DLL 由上面的 Qt6 白名单保留。
# * opengl32sw.dll（20M 软件渲染回退）删：Chromium 自带 SwiftShader，
#   冻结包深度冒烟（--open 加载页面）通过。
# * DevTools 资源包（85M）、QML 组件目录（29M）、译文、虚拟键盘、qmltooling：
#   生产分发用不到（DevTools 代价：插件页面里检查元素无资源，调试用开发环境）。
# 裁不动：Qt6WebEngineCore.dll ~195M（Chromium 本体）与 icudtl.dat 10M。
