   Footer fixes — 2026-09-18

   Giuliano: "I don't know why you added those arrows on the footer. That
   looks horrible." footer() in app.js no longer renders <details>/<summary>
   for the link columns — each is now a plain
   <div class="foot-sec"><h4>Title</h4><a>...</a>...</div>. Every rule in
   mobile-navigation.css that drew the chevron (.foot-sec > summary::after,
   .foot-sec[open] > summary::after, #app footer .foot-sec > summary) now
   targets an element that no longer exists, so no chevron is drawn on
   mobile or desktop. This file restyles the plain markup:
     - the column heading is an <h4>, not the <b> that style.css's
       .footer-grid b rule expects, so it needs its own rule here.
     - .foot-sec still carries the old mobile accordion's border/padding
       from mobile-navigation.css; reset it.
     - below 760px, lay the columns out as a compact 2-column grid of plain
       link lists (Alibaba's mobile footer), instead of the old stacked
       accordion rows.
