 * The two hard rules from design review are load-bearing here:

 *   2. Pinned width + padding always carries box-sizing: border-box.

   the content edge at every viewport, so the crop always reads as a surface
   continuing rather than a broken layout. calc(100% + 48px) keeps that bleed
   constant while the column flexes; at 1440 it resolves to exactly 760px.
