/* ---- Procedures-page-only overrides (Procedures.html) ---- */

/* Fix: a grid column's minimum width defaults to the size of its content
   (here, a fixed 10cm image box), so a full 4-across row could demand more
   width than the grid's own max-width and spill past the right edge of the
   page -- shrinking the right-hand margin to nothing on rows with 4 items
   while rows with fewer items stayed correctly centered. Allowing the
   column (and therefore the fixed-size image box inside it, via its
   existing max-width:100%) to shrink below its content size keeps every
   row -- full or partial -- inside the same centered box, so the left and
   right margins end up equal everywhere on the page. */
