/* ============================================
   Varsity Heating and Cooling — Global CSS
   Design: "Varsity Athletic — Bold & Confident"

   Aesthetic: Collegiate energy meets Pacific NW craft.
   The otter in a letterman jacket tells you everything —
   approachable, confident, team-oriented. We lean hard
   into the varsity sports feel: bold condensed type,
   diagonal energy, stripe accents, and a navy-red-gold
   palette that hits like a school fight song.
