   INDIAN PIN CODE DIRECTORY

   Palette is institutional rather than startup-blue: a deep ink navy, a
   saturated indigo for interaction, and a single postal red reserved
   exclusively for delivery status. Red appears nowhere else, so when it does
   appear it means something.

   Type: IBM Plex Sans for interface, IBM Plex Mono for every PIN code and
   coordinate. The digits are the content, so they get the face that makes
   them scannable in a column.
