/* ---- Card grids ----
   Kingdom is always exactly 10 cards, so its column count is hardcoded
   (5, or 2 on phones - see the media query below) rather than derived from
   a percentage/auto-fill guess. That guess is what broke into a 6-then-4
   split: auto-fill's column count is a function of continuous width, with
   no idea the row needs to divide evenly into 10. Only divisors of 10 are
   used as column counts here so a row is never left ragged.

   Every card also gets a fixed max-width (below) instead of being allowed
   to stretch to fill its column. Columns are capped the same way (190px,
   not 1fr) - capping the card alone isn't enough, since 1fr columns still
   stretch to fill the full row on a wide screen, which just relocates the
   dead space to between cards instead of removing it. justify-content
   centers the resulting compact block, pushing leftover width to the
   outer margins instead. */
#kingdom-cards {
  display: grid;
  grid-template-columns: repeat(5, minmax(130px, 190px));
  justify-content: center;
  gap: 0.65rem;
}

/* Bonus/Landscape counts vary each generation, so these flow naturally -
   but with the column track itself capped to the same width as the card
   max-width below (not 1fr), so a half-full row doesn't stretch into
   oversized columns; leftover space centers the whole row instead.
   auto-fit, not auto-fill: auto-fill reserves as many column tracks as
   mathematically fit the container, even ones no card occupies, and
   justify-content:center centers that whole reserved set - so with only
   1-2 cards in a very wide row, the real cards sit near the left edge of
   a mostly-empty invisible block, looking uncentered. auto-fit collapses
   the unused trailing tracks to 0 width, so centering only accounts for
   the tracks actually holding a card. */

   a portrait card (bigger, not just wider). Scaling to 80% of the span
   brings its area back in line with a portrait card's, so it reads as
   "wide" rather than "giant" next to its neighbors.
   max-width needs its own value here (not the general .card 190px) - a
   2-column span capped at 190px each is up to ~390px, and 80% of that is
   ~312px; inheriting the flat 190px cap instead would clamp it down to
