/* Kloudserv site: shared design system for every page.
   Built from Concept L (home). Apple product-page grammar: huge confident type, one idea per screen,
   real objects instead of illustrations, quiet motion that only reveals and moves real things.
   Light theme. Ink on near-white, one accent (Kloudserv amber), one dark band per page at most.
   Radius scale: 28px panels, 18px cards, 12px inner rows, pills for buttons and tags. */
