/* ============================================================
   FarmFlow Design System — main.css
   
   Design concept: "Field-to-Ledger"
   A poultry farm management app needs data density, instant 
   legibility, and calm authority. Not a dashboard template.
   
   Palette: Deep forest green primary (#1A3D2B), warm amber
   accent (#D4860A), off-white canvas (#F7F5F0), slate text.
   The green grounds the product in agriculture; the amber
   signals urgency/attention; the off-white is warmer than #fff.
   
   Signature: The left-side navigation has a solid deep green
   column — every other element respects this anchor.
   
   Typography: system-ui for data; no web font requests on
   shared hosting (avoids external requests for speed).
