/* The public home (T-SITE-B1b): concept B's hero, receipt picker and plain-
   terms close, over the shell in marketing.css.  Loaded by home.html.jinja
   only.  Same contract as marketing.css: the .mk-body site tokens or a shared
   size token for every value, logical properties only, and every transition
   or animation inside the one trailing prefers-reduced-motion block.

   Two aliases are set here rather than in tokens.css because they choose
   between site tokens per theme and nothing outside the hero reads them:
   --mh-on-sky is the text colour on the sky (paper-white over the day sky,
   the light ink over the night sky), and --mh-sky-break is where the deep band
   hands over to the light one (a step lighter by day, a step darker by night,
   so the copy below the break only gains contrast as the gradient runs on). */
