/* Antitheft web design system (scaffold).
   The antitheft desktop app's UI language, ported for the marketing page:
   tokens from antitheft/ui/src/pages/Home.css (the finalized glass look;
   the dark values are its true-neutral canvas, NOT the bluer shadcn set in
   index.css), Space Grotesk + JetBrains Mono, one accent (blue), status
   colours (good / warning / critical), light and dark. Each page adds only its
   own rules in its own stylesheet (next.css, ...), the same split the app uses.

   Layout: FULL WIDTH, no container. Sections are full-bleed and only carry
   an inline gutter (--gutter); content uses the whole width, so wide
   examples, animations and redrawn UI components have room.

   Radius rule (one scale, used everywhere): controls and chips 8-10,
   cards 16, window frame 12, dialogs 20.

   Components: .nav .wordmark .sec .h-hero .h-sec .lede .glass .card .btn
   .btn--primary .btn--ghost .iconbtn .chip (--good --warn --crit) .seg
   .codebox .window .titlebar .row (+ .actor .verdict) .emblem .reveal
   .sr-only .dev-theme .actor-logo .logo-chip .pill .ui-pic. */
