   provide: hero with dc-engineer background + overlay like primcast, stats
   bar, feature cards, value grid, OpenStack service cards, comparison table,
   region cards, and the closing CTA. Uses logical properties throughout
   for [dir="rtl"] mirroring (rtl.css).

   private cloud product, adapted to WECORE's design language.
