   sides, two lower sides), positioned with real trig around a fixed
   radius --R and sized off cqmin — the smaller of the CARD's own width
   and height, via container queries, not the viewport. That's the part
   that matters: a viewport-relative unit (vw/vh/vmin) doesn't know
   whether this card is one of three side-by-side or the only one on
   screen, so the same ball size that looks right in one layout can
   overflow or collide with itself in a narrower one. cqmin scales with
   whatever box the balls actually have to live in, and since both the
   ball size (--ct-ball) and the pentagon's radius (--R) scale together
   off the same unit, the ratio between "how big the balls are" and
   "how far apart their centers sit" never changes — so they can't
   start overlapping each other at some sizes and not others. */

     to 2.902 x ballSize wide (the row-2 side balls are the widest
     point) and 2.809 x ballSize tall (top ball to bottom row). THE TWO
     NUMBERS TO TWEAK are the 31cqw/32cqh below — each is "how much of
     the card's width/height this pentagon may use"; raise either for
