/* Grid system: Cargo Basic Grid, as observed on https://970180.cargo.site/
   Desktop: centred content with large white margins, plain white background,
   black text, no borders, boxes or shadows around images. Two items side by
   side for most of the page, with a narrow white gutter between a pair and a
   larger white gap before the next row. Images fill their item width and share
   a roughly common height, so aspect ratios vary. Caption is one left-aligned
   line under the image: number, title, date, with the date in grey.
   Phone view was NOT observed on the Cargo page (browser controls could not
   resize to phone width), so the single-column phone fallback below is our
   own implementation choice, not a Cargo observation. */
