   BHARAT ECOFUELS — RESPONSIVE ARCHITECTURE
   Mobile-first system. Single source of truth for all viewport-conditional CSS.

   BREAKPOINT SCALE
   ──────────────────────────────────────────────────────────────────────────
   xs    ≥ 360px   compact phones (iPhone SE)            mobile default
   sm    ≥ 480px   large phones
   md    ≥ 768px   tablets (iPad portrait)
   lg    ≥ 1024px  laptops
   xl    ≥ 1280px  desktops
   2xl   ≥ 1680px  ultra-wide

   PHILOSOPHY
   ──────────────────────────────────────────────────────────────────────────
   Defaults written for the SMALLEST screen. Each min-width @media block
   PROGRESSIVELY ENHANCES upward. No max-width queries; no specificity wars.
