   The wide tile keeps the row's HEIGHT and only doubles its WIDTH: aspect-
   locked cards do NOT stretch to fill a taller row, so a mismatch leaves blank
   page under the short tiles.

   With a gap this can no longer be a fixed ratio. A span-2 tile is
   `2·col + gap` wide, so `aspect-ratio: 8/3` would make it 3·gap/8 TALLER than
   its 4/3 neighbours — a few px of misalignment, which rounded corners make
   obvious. Percentage padding resolves against the element's own width, so the
   height is expressed exactly instead:

     col    = (W - 3·gap) / 4          target height = 3·col/4
     span-2 own width = W/2 - gap/2  ->  h = 37.5%  - 0.375·gap
     span-4 own width = W            ->  h = 18.75% - 0.5625·gap
