/*
 * Shared stylesheet for the /insights/ section.
 *
 * The rest of the site inlines its CSS per page, which is fine for five pages
 * that rarely change. Articles are different: they get added weekly, so
 * duplicating ~250 lines of design tokens into every new file would guarantee
 * drift. This file carries the same tokens and component styles as the inline
 * versions — keep them in sync if the main pages are restyled.
