/* ============================================================
   KeyVC — Main Stylesheet
   keyvc.co
   
   HOW TO CUSTOMISE:
   ─────────────────
   • Brand colors  → Edit :root variables below (section "BRAND")
   • Logo text     → Search for class .logo-text in index.html
   • Logo image    → Replace images/logo.svg with your file,
                     then in index.html change .logo-mark to:
                     <img src="images/logo.svg" alt="KeyVC" class="logo-img">
                     and add: .logo-img { height: 32px; width: auto; }
   • Fonts         → Change the Google Fonts @import URL and
                     update --font-display / --font-body below
   • Copy/text     → All page text lives in index.html only
