  /* On a narrow phone the hero is very tall (everything in .hero-in stacks
     into one column below 1000px), but the source footage is a fixed 640x360.
     Left at inset:0 the video was forced to cover that whole tall box, which
     meant scaling it up until only a thin vertical sliver of the frame was
     visible — a blurry, unrecognizable crop.

     This aspect-ratio is the no-JS / before-JS-runs fallback, so there is
     never a flash of the old full-height stretch. main.js then measures the
     real position of the "Drive With Us" / "Ship Freight" buttons and sets
     an explicit inline height reaching just past them — see
     heroVideoMobileHeight() — which overrides this. max-height is a sanity
     cap for that JS value (very large accessibility font sizes, unusually
     short viewports) set high enough that it should not bind on any real
     phone in portrait — if it does, the video simply ends a little short of
     the buttons rather than overflowing past them. */
