/* 1-Rep Max Calculator — content styles.
   Prefix: --rm-  /  .rm-

   Reference point: a gym-plate-inspired bold numeral display for the
   hero figure — the audience wants one big number fast, then the
   breakdown. High-contrast, heavier weights than this loop's other
   calculators, since the subject itself (barbell training) calls for
   a bolder, more physical feel than a financial or writing tool.
   Ninth `health`-cluster tool built this loop.
