/* =========================================================
   header.css — DutchLine Header v4 (B2B)
   Works with your HTML exactly as posted.
   Notes:
   - Uses existing theme vars if present: --border, --border2, --panel, --text, --muted, --accent, --focus, --shadow, --shadow2, --r, --r2
   - Adds fallbacks so it still looks good if some vars don't exist
   - Mega menu opens via: .dl-mega.is-open .dl-mega-menu
