   DESIGN SYSTEM: "ARCHITECTURAL BLUEPRINT"
   ─────────────────────────────────────────────────────────────────────────
   Aesthetic : Light editorial meets architectural precision. Drafting room
               elegance — blueprint grids, engineering line weights, copper
               hardware tones. Premium residential contractor that reads like
               a luxury architecture firm, not a contractor ad.
   Theme     : Predominantly light. Off-white paper base. Deep navy anchors.
               Copper accent for warmth and premium feel.
   Mood      : Trusted. Precise. Substantial. Not aggressive, not generic.
