/* ---------- grid ----------
   Measured against David Zwirner, Fraenkel and Pace -- see
   Projects/GALLERY-DENSITY-RESEARCH-2026-08-24.md.

   Two plates per row. A SMALL horizontal gutter against a VERY LARGE vertical one
   (Zwirner runs 20px : 138px, a 1:7 ratio) -- the luxury is vertical, not padding
   round each picture. Each plate sits inside a fixed 4:3 cell at object-fit:contain,
   so a portrait picture is letterboxed by the page's own paper ground exactly the
   way a mat surrounds a print in a frame. Nothing is ever cropped.

   Grid, not CSS columns: multi-column fills column one top-to-bottom before it
   starts column two, which sends a sequenced gallery into the wrong reading order. */
