   Landing Nitrea Pupuk Urea 46% N — pro.phonskaman.com/landing
   Sistem desain bespoke (tanpa Tailwind): "precision agri-industrial".
   Ide fokal redesign: karung Nitrea = spesimen di panggung instrumen agri-tech
   (ghost spec type, HUD badge berkonektor, lantai wireframe, spec panel gelap).
   Palet OKLCH + fallback hex. Konten SELALU terlihat tanpa JS; animasi
   hanya menyempurnakan (progressive enhancement, lihat public/js/nitrea.js).
