/* ============================================================
   NovaSol Energy — styles.css  (shared by all pages)
   Brand: "Energy, Responsibly"
   ------------------------------------------------------------
   HOW TO EDIT SAFELY:
   - Brand colors live in :root — change once, updates everywhere.
   - Each component has its own commented block below.
   - Copy/text changes belong in the .html files, not here.
   ------------------------------------------------------------
   DESIGN NOTES:
   - Light, corporate look: white / soft backgrounds, no heavy
     solid-color bands.
   - Orange/gold + green (from the logo) are the lead accents;
     navy is reserved for headings and text.
   - Headings use Poppins (rounded, matches the logo wordmark),
     body uses Inter.
