   The single-article layout was only ever tuned at desktop sizes, so on a
   phone the shell, the hero, the TOC block and the footer kept their wide
   values. Most of the dead space came from the grid gap: below 1080px the
   layout collapses to one column, and a 48px row gap that reads as a
   comfortable gutter on a wide screen becomes a hole between the TOC and
   the first paragraph on a phone.
