/* Geotechnology menu group (WS-957, WS-967; INVENTORY task 1). Linked by the masthead (sitebuild/sitemap_menu.py
   header) only while site.config.json geotech.pages shows the group, so a build with the switch off keeps site.css and
   mega-menu.css (and every page's ?v= stamp) as they were. Seven groups fit the desktop bar only without the word
   "Strature" before Briefs, GPS and Advisory: the prefix is dropped on screen at every desktop width (site.css already
   did so from 900 to 1199px), as a clip, so screen readers keep the full names ("Strature GPS"). The phone sheet is
   unchanged: one more accordion row. */
