    steps:
      # ==========================================
      # 1. Checkout 原仓库
      # ==========================================
      - name: Checkout original repository
        uses: actions/checkout@v4
        with:
          ref: main
          fetch-depth: 0
      # ==========================================
      # 2. Clone Fork
      # ==========================================
      - name: Clone fork repository
        run: |
          git clone \
            --depth 1 \
            --branch main \
            "https://github.com/SnapHutaoRemasteringProject/Snap.Metadata.Work.git" \
            ../fork
      # ==========================================
      # 3. 显示同步前后的 Commit
      # ==========================================
      - name: Show source commit
        working-directory: ../fork
        run: |
          echo "Fork commit:"
          git log -1 --oneline

        run: |
          echo "Original commit:"
          git log -1 --oneline
      # ==========================================
      # 4. 同步文件
      #
      # --delete：
      #   Fork 删除的文件，原仓库也删除
      #
      # 排除 .git：
      #   不复制 Git 元数据
      #
      # 排除 .github/workflows：
      #   原仓库自己的 Workflow 永远保留
      # ==========================================
      - name: Sync files
        run: |
          rsync -av --delete \
