   Eigenständig. NUR auf den beiden Inhaltsseiten enqueuen:
     · Servicepartner          (Page 1160, DE)
     · Frequency Management    (Page 824, EN)
   Alles unter .sd-content-page gescoped, damit der übrige Shop
   unberührt bleibt. Tokens identisch zum Design-System
   (colors_and_type.css). Liegt der globale Token-Block (z. B.
   sdlink-home.css / sdlink-tokens.css) bereits vor, kann der
   :root-Block hier entfallen (Werte sind identisch).

   Schwester-Vorbild: design_handoff_faq/ + design_handoff_kontakt/
   (gleiches Muster). Icons im Markup sind funktionale Inline-SVG
   (Lucide-Stil), eingefärbt über currentColor.
