The logo row with nothing moving in it: marks sitting still in ruled cells, which is the same shape a rack of machines comes in. A rail that travels says there are many of us; a rack that sits says these are the ones we run, so it is the right row under a fold about infrastructure rather than under one about reach. Every rule is the gap showing through a filled parent rather than a border on a cell, so a cell that wraps to a new line cannot double a rule up with its neighbour's and the hairline stays exactly one pixel at any column count. Two columns on a phone, four on a tablet, eight on a desktop, and the label sits over the rack rather than beside it because a rack has a top edge to hang from where a moving track does not. The marks are brand-showcase's, painted in currentColor through muted-foreground, so they follow the host's theme instead of being inverted into it, and a cell lifts to full ink on hover. Lifted out of hero-04 as a copy rather than an import: a section that had to pull in a whole hero to draw eight logos would install the plane, the nav and the copy with it. No dependencies and no client boundary.
