/* DNEG AI Roadmap: site.css
   1. Base and ambient background          (from the Gate LLM presentation, minus the full-viewport scene engine)
   2. Components ported from the presentation, class names unchanged:
      .eyebrow .title .lede .frag .grid .card .chip .btn .pill .stats .stat .hosts .bars .bar .steps .step .tl
      .legend .four kbd code .mono .num
   3. Site layout: .topbar .lens-nav .search .filterbar .layout .rail .main .footer
   4. Site components: .sechead .hero .section .tag .owners .tiles .lens-grid .rlist .rrow .panel .empty ...
   5. Responsive, print, reduced motion
   Colours come from tokens.css only. Per-lens extras live in css/views/<lens>.css. */
