/* Wallpaper Roll & Pattern Repeat Calculator — content styles.
   Prefix: --wp-  /  .wp-

   Reference point: a hero "rolls needed" whole number leads, since
   that's the number a visitor is actually going to buy against, backed
   by a 3-metric row showing the intermediate strip math so the pattern-
   repeat waste is visible rather than hidden inside a single figure.
   First home-diy-cluster tool built this loop.
