   Blocksy 实际输出的页脚结构（已核实）：

   footer.ct-footer[data-id="type-1"]
     [data-row="middle"] > .ct-container[data-columns-divider]
        [data-column="widget-area-1"] … [data-column="widget-area-4"]
     [data-row="bottom"]  > .ct-container > [data-column="copyright"]
   ---------------------------------------------------------------
   四个小工具区域的内容是用核心区块写的，James 以后可以在
   后台「外观 → 小工具」里直接改，不用碰代码。
