/* --- Benchmark figures ---------------------------------------------------
   The charts are `<img>`-referenced SVG (docs/charts/), so they scale with
   the column like any image. That is right on a wide screen and wrong on a
   narrow one: a uniform downscale takes 11px axis labels to about 5px, and a
   chart you cannot read the axes of is decoration.

   So below the tablet breakpoint they stop shrinking and the figure scrolls
   sideways instead — the wide-content rule, applied to the one kind of wide
   content this site has. Selected on the src path rather than a wrapper class
   so the markdown stays exactly what GitHub renders, which is the whole
   reason these are files and not inline SVG. */
