   Video-forward layout per client brief: full-bleed hero
   video, then four alternating left/right feature blocks
   (video one side, heading + sub-line + paragraph + CTA
   the other), a device-compatibility logo row, and a
   closing CTA band. Modelled on the 3DVista home pattern.
   Layout via Bootstrap .container; brand styling here.  */
