   Concept: "The Connecting Dots"
   Experience = scattered dots. Read through context, they connect
   into a growth structure.

   Design language: editorial black & white. White paper, near-black
   ink, a continuous dot-network reading quietly on white. A single
   accent — a vivid, deep blue — used sparingly for connection.
