   ALMADAD CHEMICAL INDUSTRIES — Design System
   Concept: "Industrial Dossier" — the site is styled like a
   technical specification register (SDS / ISO document set):
   clause-numbered sections, mono data strips, hairline
   blueprint-grid texture, and an amber/red "process" marker
   used the way a chemist annotates a data sheet.
