/* Best Choice Heating & Air Conditioning — Design DNA
   Register: BRAND
   Mood: San Antonio desert-adobe warmth — a stucco courtyard at dusk, not a
   sterile blue HVAC-tech dashboard.
   Anchor refs: adobe brick wall at golden hour, a wall-mount thermostat dial,
   a Southwest turquoise pendant used sparingly as jewelry, not paint
   Color: warm terracotta-sand canvas, deep umber ink, flame-orange brand accent
   (heating), a small desert-turquoise pop reserved only for cooling mentions
   (Committed palette, warm-dominant — no blue/steel-gray as a base)
   Type: Bitter (slab serif display) + Karla (grotesque-humanist body)
   Layout: asymmetric split-screen hero (text left, dial gauge right)
   Motion: calm, slow draw-in — quint easing
   Signature element: animated thermometer/dial gauge with a sweeping needle,
   settling on a "just right" mark
