/* ---- collage grid (the magazine layout) ----
   Only the column span is fixed. Row height comes from each image's
   inline aspect-ratio, so the image is rendered at its true ratio with
   ZERO cropping. Items inside the same row align to the top; a slightly
   shorter image leaves visible whitespace below it — that's the price of
   "keep original ratio" and it's the editorial / magazine look. */
