   PiPO HRIS — LAYER 22 · CALCULATORS
   The brief: simple, not clever. Someone who has never run a payroll should be
   able to open one of these, type one number, and understand the answer.

   So: one question at a time, plain words, big readable fields, and a result
   panel that leads with the single figure that was actually wanted. Anything
   that is not needed to get an answer is behind a disclosure. Notes sit below
   the calculator, never beside it.
