   CRO-specific sections: the two "key services" panels, the tabbed
   expertise cards with their decorative visuals, and the dark CTA
   panel. Shared pieces (hero, section-head, why-cards, partners) come
   from components/. The examples' amber second-accent is dropped —
   the two-of-a-kind distinctions (ks-01/ks-02, the two domains) are
   carried by teal vs. blue instead. */
