/* ── Flow diagrams (case pages) ──
   Boxes are HTML, so they grow with their labels instead of overflowing a fixed drawing.
   Below 960px the items stack in source order and only .step arrows are drawn, pointing down;
   a .flow-pair puts a side input beside its target, joined by a .side arrow.
   From 960px the box widens past the text column and the items sit on a grid: the diagram sets
   its columns with --cols (and an optional --max width) and each item its place with --at (a
   grid-area value). A .c cell draws lines from its center to the edges named by l, r, t and b,
   with an arrowhead at the edge named by to-l, to-r, to-t or to-b. A .fill box stretches to its
   row's height; a .fit box wraps to its column's width instead of widening the column. */
