/* OpenCore marketing sites — shared design layer.
   Apple-inspired commercial style: calm, premium, spacious, product-focused.
   The UI is almost entirely black / white / greyscale; colour lives in photos and
   product imagery, not in the surrounding chrome. A single calm blue accent appears
   only on text links, small active states, and secondary CTAs.

   All values come from the design-token profile in tokens.css (imported below).
   This stylesheet references SEMANTIC tokens only — never raw primitives — so the
   whole look can be re-skinned by swapping the profile. Zero build: plain CSS. */
