/* ==========================================================================
   Sioux Falls HVAC Repair — site.css
   --------------------------------------------------------------------------
   PERFORMANCE NOTES (why this file looks the way it does):
   - One small stylesheet for the whole site. Cached after the first page view,
     so every subsequent page (service -> location -> contact) is near-instant.
     That matters because the money path is Home -> Location -> Call.
   - No webfonts. System font stack renders on the first paint with zero network
     requests and zero layout shift (protects LCP + CLS in Core Web Vitals).
   - No CSS framework. Tailwind's build step + purge config is a maintenance tax
     on a static lead-gen site the owner will edit by hand. Hand-rolled CSS here
     is ~31KB on disk (heavily commented) but ~8.6KB over the wire with gzip,
     and it does exactly what the conversion layout needs. Strip the comments
     at deploy time if you want it smaller; do not strip them in the repo.
   - Mobile-first: every base rule targets the phone. Desktop is the override.
     70-85% of "hvac repair near me" traffic is mobile, usually on a furnace
     that just quit. The phone layout IS the product.
