/* ==========================================================================
   ZCU IMPACT TRACKER — Zen Coast brand system
   Palette and type from the Zen Coast brand deck (Emma Linh, Jan 2021):
     Pure White  #FFFFFF
     Ink Black   #000023   (a blue-black, not a flat black)
     Ocean Spray #88DBDF   wash #DCF7F7
     Mariner     #0047BB
   Headlines: Garamond, "a humanist serif ... authority with warmth"
   Body:      Montserrat, "a friendly and distinctive geometric sans-serif"
   The deck's design principles are load-bearing here, not decoration:
   white space, not busy. So the surfaces stay white, the rules stay hairline,
   and Mariner is spent sparingly on the things that matter.
