/* ==========================================================================
   তিরিশ — the poultry dealer's credit book
   Palette taken from the shop itself: a wall of printed poly feed sacks.
   Bangladeshi feed sacks (Nourish, Kazi, Paragon, Aftab) are one deep ink-blue
   printed on bright white poly, with a hard stencil red for the weight mark.
   So: cool poly white ground, sack blue for everything structural, stencil red
   reserved for one thing only — a flock past its lifting day with money still out.
   Deliberately not Doorstep's spruce, not Akhra's board, not Pathshala's ruled
   paper. No cream, no terracotta.
