/* Large screens / TV display — every size below is clamp()'d against
   min(vw, vh) so it scales with whichever dimension is tighter. A wide
   4K TV and a wide-but-short tablet in landscape both hit this query;
   without the vh half of the min(), the tablet case overflows vertically
   and forces a scrollbar instead of shrinking to fit. */
