/* ─── CarSearch AI: the one design system for car-search.ai, partners.car-search.ai and websites.car-search.ai ───
   Evolved from the Partners landing (landing.css): navy hero with blue and amber glows, tracked eyebrow, 800-weight
   headings, device frames, ink footer. Every colour is a token on :root; dark mode is the same tokens re-set.
   Components are prefixed cs- so the file can sit beside a page's own stylesheet without clashes. The buttons and the
   device frames keep the landing's names (.btn, .device) because the three pages share that markup.
   Identical copies: WebSite_v3/public/css/csai-site.css and CarSearchAIPartners/app/public/css/csai-site.css. */
