/* insight-editorial-v2.css: shared layout layer for insight articles.
 *
 * Linked from every /insights/<slug>/ page straight after base.css, so a
 * page's own inline <style> still loads later and wins where it styles the
 * same component. It adds no fonts and does not restyle running text.
 *
 * The components follow the reference layout of
 * /insights/emerging-ai-agent-infrastructure-stack/: the "In this article"
 * contents box, the pull quote, the axis table and the layer stack. Any
 * article can use them without copying their CSS inline.
