/*!
 * Sarv Catalyst — Insights and News
 *
 * Loaded on the insights index (WordPress's posts page) and on the news page, and
 * nowhere else. Like the Contact, catalogue, Industries, Services and company
 * stylesheets it is not part of the shared ladder: it loads after `utilities.css`
 * and therefore wins a tie against a rule there.
 *
 * The two pages share one file because they present the same thing — a list of
 * published articles drawn with this site's editorial language rather than a blog
 * theme's grid. Sharing it is what keeps them from diverging.
 *
 * Everything below reads the approved design tokens. No value is invented, no
 * colour is written as a literal, and every offset uses logical properties.
 *
 * Cascade order in this file:
 *   1. Hero
 *   2. Category topics
 *   3. Featured article
 *   4. Article list and pagination
 *   5. Empty state
 *   6. Responsive
