/* ============================================================================
   GO4AI — Homepage proposals (2 variants)
   Design system ported from b2b.go4ai.org
   Source of truth: LucasGo4ai theme
     · go4ai.webflow.shared.72c645715.min.css  (tokens + component classes)
     · inline <style> in the published page    (gradient, marquee keyframes)

   Token values are copied verbatim from the live theme :root.
   Font note: the theme declares Switzer for headings, but the published
   Switzer woff2 files are latin-only subsets with no Vietnamese tone marks.
   Headings therefore use Archivo (full Vietnamese coverage) — the same end
   state the live site reaches via fallback, but deterministic.
