   2. Grid layouts — count 1 through 6
   CSS only defines layouts up to 6. The JS DISPLAY_CAP constant
   must match: posts with 7–10 images show 6 tiles + "+N" overlay.

   Counts 2–6 use aspect-ratio: 1/1 on tiles so all grids are
   square-cropped regardless of original image orientation.
   Count 1 is never cropped — always shown at natural size.
   Count 3: right two tiles are square; left tile spans both rows
            and becomes a natural tall portrait strip.
   Count 5: first tile is a wide landscape hero (2:1 ratio auto-
            computed from 3-column layout); tiles 2–5 are square.
