   CLOUBAY — Warehouse Racking Systems
   Design system. Industrial B2B palette taken from the category leaders
   (Mecalux / Dexion / AR Racking / SSI Schaefer) and from the product itself:
   blue uprights + orange beams. Flat colours, hard corners, hairline rules.
   Typography: universally installed grotesques only. No web fonts.
