   A separate band BELOW the pricing cards, not a third card: the two-card grid
   is fixed at 2×24rem and squeezing a third column in would shrink the lifetime
   card, which is the page's primary conversion target. A distinct band also
   reads correctly — this is an optional extra, not a third plan to compare.

   The refund notice is deliberately part of the card, not fine print at the
   bottom of the page: a .json file loses its value the moment it is opened, so
   "no refunds" has to be visible BEFORE the buy button, not after. */
