   ARI Public – Design system
   Visual language of caralegal.eu/lp/ai-flow: one uniform warm-cream
   surface, generous and consistent vertical rhythm, hairline-bordered
   cards on the same cream (no value contrast, no section tinting),
   restrained purple + lime accents, one dark block before the footer.
   A floating navigation pill that narrows on scroll.
   No external fonts, no external JavaScript libraries.
