   because the sidebar breakpoint at 1000px changes available width) the 14-card
   span mix occupies 20 cells - not divisible by 3, so dense packing always leaves
   one cell empty (the reported bottom-right gap). Nowhere else is touched: 2, 4

   additional plain card a 2-column span ONLY in this container-width band brings
