/* Hero mockup — dock styles ported from the Adnota (ex-Vellum) extension.
   Source: webrevise/content/dock.css + webrevise/lib/vellumUI.css.
   Every rule is scoped under .hero-mockup so identical class names (e.g.
   #vellum-dock, .vellum-dock-tool) cannot leak into the rest of the site.
   Two deltas from the extension's version: position is absolute (scoped to
   .browser-body) not fixed, and there is no idle-opacity dim — the demo
   dock is always at full opacity. */

/* Full-width flex column so .browser-wrap's `width: min(900px, 100%)` keeps
   resolving against the hero's full content-width, and the caption pill
   stacks directly beneath the mockup. */
