   Service — Technology, Variant 2 (Stack Explorer). Same component as the
   Real Estate App Development page's own Services section
   (assets/css/real-estate-app-development.css `.reapp-svc-*`) — the same
   component already reused once for Our Services Variant 1
   (assets/css/services/our-services.css `.our-svc-*`) — reused again here,
   renamed `.svc-tech2-*` (its own namespace). A dark heading band over a
   white, elevated panel with a numbered item list on the left and a
   synced detail panel on the right. Variant 1 needs no CSS here — it
   reuses the sitewide `.service-tech-*` classes in main.css.

   animated handler in main.js with zero new JS — the `.svc-tech3-*`
