   Saltwater & Steel — Fencing & Gates (Newcastle NSW)
   Bespoke design system. Grounded coastal-steel: warm limestone paper, warm
   charcoal ink, powder-coat eucalypt + weathered timber + deep cove teal.
   Motifs: vertical paling rhythm, monospace spec chips (like a fab drawing),
   a "post" left-border on cards. Nothing here is shared with another node.
