   VTM Brand & Design System 4.2 — Produktions-Build
   --------------------------------------------------------------------------
   Enthält: Webfonts (selbst gehostet), Tokens, Base, Komponenten.
   Quelle: _ds/vtm-design-system-* aus dem Design-Export.

   ABWEICHUNGEN vom Export (bewusst, dokumentiert):
   1. @font-face statt @import von Google Fonts
      → keine Drittanbieter-Requests (DSGVO), kein Render-Blocking.
   2. --text-muted: #6e7888 → #666f80
      → #6e7888 erreicht auf Weiß nur 4.46:1 und auf --surface-soft 4.35:1
        und verfehlt damit WCAG 2.2 AA (4.5:1). .meta / .kicker nutzen diese
        Farbe bei ~13px und gelten NICHT als "large text".
        #666f80 liefert 5.06:1 (weiß) bzw. 4.80:1 (paper-blue).
      → Primitive --c-neutral-500 bleibt unverändert.
   3. --research: #9b7017 → #8f6715 (4.45:1 → 5.10:1), gleiche Begründung.
   4. Source Serif 4 wird nicht geladen: auf dieser Seite kommt
      --font-editorial nicht vor. Der Fallback-Stack bleibt erhalten.
