   Colour   : Deep maroon (heritage/gamosa red), turmeric gold, tea-garden
              green, warm parchment cream, ink charcoal.
   Type     : "Yatra One" (display, Indian-inspired serif-slab) for
              headings; "Karla" for body/UI; "Mukta" for Assamese-flavoured
              accents/labels.
   Signature: A woven "gamosa stripe" border motif (the red-on-white
              Assamese ceremonial cloth) used as section dividers, and a
              horizontal "district ticker" listing HYCP's district units.
