/* Screen PPI Calculator — content styles.
   Prefix: --pp-  /  .pp-

   Reference point: a crisp, display-adjacent cool-neutral — the third
   files-media-cluster tool this loop, hue-differentiated from the
   warmer audio tool and the cooler file-transfer tool by leaning
   slightly blue-grey, evoking a screen/display rather than a file.
