/**
 * Variant CSS: nav--icon-row-compact
 *
 * Compact single-row header where every menu item is a small inline SVG icon +
 * label, closed by a pill CTA. The icons give a quick, app-like read of the nav
 * and act as visual anchors. Icons inherit currentColor, so they track the link
 * colour and lift to --accent on hover. Mobile: the menu drops as a panel, the
 * icons stay beside their labels. Uses the chrome tokens
 * (--text-primary / --background / --divider-primary / --accent).
 * Scope: body.aibt-universal .universal-nav--icon-row-compact.
