/* AI-native company doc. Same look as the /resources hub (resources.css): white canvas, system type, quiet colour.
   The navbar is styled by site-nav.css. ai-native.js reads #doc, .doc-frame (+ .open), .copy-toast (+ .visible),
   [data-copy-doc] (+ .copied) and [data-expand-doc]: keep those hooks. */
