   Tricity Stove Service — Stylesheet
   Palette: "Kitchen Flame" — Charcoal Ink + Burnt Terracotta + Sage + Warm Cream
   A theme built around the two things this business actually touches every
   day: cast-iron/steel appliances (ink, charcoal) and the flame itself
   (terracotta, amber). Sage stands in for WhatsApp so it reads as its own
   distinct action, not a generic blue link.
