📐 How It Works

  1. Sundial calculates sun position based on time, date, and approximate latitude (cached offline)
  2. Hold phone at calculated angle—shadow forms on the screen
  3. Shadow direction reveals cardinal directions (North/South/East/West)
  4. Pre-downloaded maps show shadow-matched routes to nearest stations
  5. Local motorbike couriers are alerted via offline mesh network
