/* ============================================================
   Meridian Air — styles.css
   Concept: "Comfort you can watch arrive." The hero is a live
   thermostat that restores a home from 82° & humid to 72° &
   perfect. One physical scalar (a comfort value 0→1) drives the
   dial's color from warm amber (struggle) to cool blue (perfect);
   the same two accents recur across the page with fixed roles:
     --blue  = comfort / cool / brand / CTA
     --amber = heat / the problem / the moment of restoration
   Type: system sans (display via weight+tracking, body via calm),
   system mono reserved exclusively for data (temps, times, stats).
