         <div class="col-lg-4"><aside class="blog-toc" id="blogToc">
             <h3 class="blog-toc-title">…</h3><nav></nav>   ← nav filled by JS
         </aside></div>
         <div class="col-lg-8">
             <div class="blog-inner-img">…</div>            ← becomes "Introduction"
             <div class="blog-content"> …h2/h3 sections… </div>
         </div>
       </div>
     </div>
