/* ============================================================
   NORTHLAND SNOW & LAWN CO — fictional client demo, internal to
   Twin Cities AI Partners. Palette: slate-navy (winter) + safety
   orange (CTA/plow-truck accent) + evergreen (summer/landscaping).
   Fonts: Space Grotesk (display) + Inter (body).
   Signature: a literal Winter/Summer toggle drives the hero —
   this business IS the seasonal switch, so the switch is the page.
