/* CAPPED EDITORIAL SCALE
   The comp is a 1024px-wide artboard where 1rem = 16px, so 1.5625vw
   reproduces it exactly at 1024.
   The upper clamp is the important half: it STOPS at 18.75px, which is
   reached at a 1200px viewport. Past that the composition is frozen and
   the extra viewport width becomes white space, instead of every element
   inflating with the window. Without that cap a 1440 screen rendered the
   design at 1.4x and it read like a presentation board rather than an
   editorial page. */
