/* ============================================================================
   Jal Sanchay Mitra — design system. Hand-written (no Node/Tailwind build step
   needed on the server — Mitra Playbook: prefer zero-dependency solutions),
   compiled once, shipped static. A "water & soil" palette: deep teal (water),
   warm earth accent, calm neutrals. Built mobile-first and BIG on touch
   targets — the primary users are non-technical field enumerators on phones.
