+Fluent Design 配置界面（PySide6 + QFluentWidgets）
+
+功能要点：
+- 拆分「通用」与「高级」两页，符合需求
+- 内置 GPU 模板：CPU/libx264、NVIDIA(NVENC/cuda)、Intel(QSV)、AMD(AMF)
+- 与 Pydantic Config 对接：即时校验，错误信息以 InfoBar 呈现
+- 生成/预览 ffmpeg 命令；可对单文件执行（subprocess.run）
+- 可导入/导出配置（JSON）
+
+依赖：
+    pip install PySide6 qfluentwidgets pydantic
+
+注意：
+- 按需在同目录准备 main.py，导出：
+    from pydantic import BaseModel
+    class Config(BaseModel): ...
+    def get_cmd(video_path: str | Path, output_file: str | Path) -> list[str]: ...
+- 本 UI 会在运行前，把实例化后的配置对象挂到 main 模块：`main.config = cfg`
+  若你的 get_cmd 内部使用全局 config，将能读到该对象。
