   measure for a wall of photographs. At 880px a 1512px laptop showed three
   columns of tiles with a third of the screen empty on each side. The grid now
   takes the width it is given, capped only where a line of 178px tiles stops
   being scannable (--content-w-photos), with gutters that shrink with the
   viewport instead of holding 20px on a 390px phone. The prose note below keeps
