   SMR PLUMBING & HEATING — Design System
   Aesthetic: Texas-bold, industrial-premium. Navy dominant with
   Texas-red + metallic-gold accents. The brand's signature
   PLUMBING(water-blue) vs HEATING(flame-orange) duality is built
   into the component system. Distinctive type, asymmetry, motion.
