   mtplus.css — the MT+ product page (site_mtplus.html), 1.3.0 overhaul

   Dark hero with the download card (the home hero's language), then the
   three headline features as alternating picture rows, each picture in an
   app-window frame. Port Verification is the big one, so it sits on a dark
   panel; the Certified test gets the same treatment, since it is how a tech
   tries it. Maintenance Tool vs MT+ comparisons read left to right: the long
   list of MT steps against the one MT+ step.
