/* Mobile article contents: at <=1000px the side TOC (which used to stack as
   a static 11-link list above the article) is replaced by a sticky bar under
   the topbar. The bar names the section being read; tapping it opens the
   full list as a dropdown. Built by TOC_MOBILE_SCRIPT from the existing
   .toc links, so without JS the original stacked list still renders. */
