/* No max-width: the panel is ~928px at full size and the facts band wants all
   of it. At 760px the band folded to 2×2 and left 168px empty on the right.
   Container queries, not media queries: the 3D viewer takes the left half, so
   this panel's width does not track the viewport — at a 1440px window it is
   594px, and a viewport breakpoint would fold it at the wrong moment. */
