      # 'cached' optimizes mount performance on macOS/Windows.
      - ..:/workspace:cached
      - test-elm-devcontainer:/home/container-user/.elm
      # --- Alternative for Neovim config ---
      # Instead of COPY in Dockerfile, you could mount it here:
      # Ensure the source path '../.nvim' exists in your project root.
      # - ../.nvim:/root/.config/nvim:cached
      # --- ADD THIS LINE ---
      # Mount the project's nvim config into the root user's config dir
      # Source: ./.config/nvim (relative to this docker-compose.yml file)
      # Target: /root/.config/nvim (where nvim looks when run as root)
      # - ./.config/nvim:/root/.config/nvim:cached
    # Command to run when the container starts.
    # 'sleep infinity' keeps the container running indefinitely so VS Code can attach.
    command: sleep infinity

    # The service will run as 'root' because that's the last USER in the Dockerfile.
    # You could explicitly set 'user: root' here if desired.
