   Business Apostle Retirement Calculator
   Design tokens follow The Business Apostle brand system (Wordmark Edition v1.0):
   Apostle Gold is the accent, navy carries the message, white and parchment
   carry the reading. A small functional set (success / caution / alert) is used
   ONLY for status and chart encoding, never as a brand accent, and is always
   paired with words and shapes so colour is never the only signal.
