/* ============================================================
   Calder Valley Plumbing & Heating — demo site
   Fictional Yorkshire plumber. Portfolio piece by Greenshields Studio.
   Design language deliberately DIFFERENT from greenshieldsstudio.com:
     - Warm cream paper instead of cool off-white
     - Burnt orange accent instead of forest green
     - Fraunces (variable serif) for display + Manrope for body
     - Trades-friendly: bold, warm, trustworthy
