/* ============================================================
   PATINAGE TEHRAN — design tokens
   Palette rationale (color psychology, chosen for this rebuild):
   - Warm off-white background: open, airy, modern — not gloomy
   - Teal/ice as the primary color: calm + trustworthy, and ties
     back to the "ice" identity of the shop
   - Coral used ONLY on action buttons: warm + energetic, and
     forms a cool/warm complementary contrast against the teal —
     this contrast is what makes "Ask on WhatsApp" etc. pop
     without the page feeling loud or aggressive
   - Soft green reserved for the "pay on delivery" trust badge —
     green reads as safe / confirmed to shoppers
