/* ============================================================
   Key figures — the container owns the grid and the gap; the cards carry no
   margin. Ported from the mockup's .metrics / .metric (styles/lithography.css
   + the light treatment in styles/product.css).

   Deltas from the mockup, deliberate:
     · the default grid FITS the number of cards (auto-fit) instead of always
       cutting four tracks, so three cards fill the row instead of leaving a
       hole. The mockup's fixed four is still available as columns: 4;
     · the label is --color-text-muted, not --color-text-subtle. The mockup's
       own product.css already made that fix (5.7:1 vs 2.8:1 against the card);
       the hero copy of the row had been left behind on the failing value.

   wrapper, so the row cannot put a class on it. :where() drops the dark
