   Section index (approach.html) and site map (site-map.html)
   Both open on the shared section-index hero from offer.css (.offer-hero--index,
   as on products.html and applications.html). Below it:
   approach.html → .pcards--2 in the hero, then "On these pages": each page's
     parts as numbered, fully clickable rows in the .qlist idiom.
   site-map.html → .smap: one band per menu section, numbered as in the menu,
     its pages as display-type rows with their parts underneath.
   Both lists are generated by tools/partials.mjs from partials/structure.json.
