/* Concrete Slab & Bag Calculator — content styles.
   Prefix: --cs-  /  .cs-

   Reference point: a materials-yard, job-site register — dense
   concrete grey neutrals and a plain bordered table for the bag
   count, since a contractor or DIYer reading this on a phone at the
   hardware store wants the number fast, not a decorated result card.
   Second `home-diy`-cluster tool this loop, after
   `wallpaper-roll-and-pattern-repeat`.
