     • Sharp 90° corners, drafting brackets, fonts
   Product-specific (varies per product):
     • Background tone: burgundy here, navy in Estimator, sage in Receipts
     • Secondary accent: dusty rose here (#E5A0B0), cyan in Estimator,
       terracotta in Scheduler — used for // MISSION BRIEF, h3 headers, links
