   Concrete Townsville — Bold component library
   Industry: concrete contractor | Location: Townsville, QLD (tropical north)
   Palette rationale: graphite/concrete neutrals grounded by a warm off-white
   "poured concrete" paper tone, driven by a hot construction-safety orange
   accent (sun, tropical warmth, high-vis trade cues) and a deep steel-blue
   secondary for trust/authority. Slab-like, high-contrast, trade-honest.
