   Dubai Repair Masters — styles.css
   Design thesis: warm/cool duality. Brass (Dubai gold, electrical spark,
   craftsmanship) against teal (the cool air of AC, the water of plumbing).
   A maintenance company fixes the hot and the cool. Everything derives
   from this. Dark/light sections alternate as a "hot → cool" rhythm.
