/* Colour is an EVENT, not a constant: the sky gradient is spent on the hero, the home splash and

   field behind body copy is what made the old page read heavy, and it forced navy-on-sky, which is
   one hue doing two jobs.

   Two ink scales, because there are two grounds. --text/--text-dim are tuned for white; --on-sky
   and --on-sky-dim for the hero, where the *deep* end of the gradient (--sky-bottom) is the worst
   case and is what they clear 4.5:1 against, not the pale end, where anything looks fine.

   The Play developer-page header wears --sky-top/--sky-bottom too; see
